+# Converters
+
+Since many drop-in replacement controllers now exist, we've done our best to make them easy to use in existing designs.
+
+This page documents the handy automated process for converting keyboards.
+
+### Supported Converters
+
+Currently the following converters are available:
+
+| From | To |
+|------------|-------------------|
+| `promicro` | `proton_c` |
+| `promicro` | `kb2040` |
+| `promicro` | `promicro_rp2040` |
+
+See below for more in depth information on each converter.
+
+## Overview
+
+Each converter category is broken down by its declared `pin compatibility`.
+This ensures that only valid combinations are attempted.
+
+You can generate the firmware by appending `-e CONVERT_TO=<target>` to your compile/flash command. For example:
+
+```sh
+qmk flash -c -kb keebio/bdn9/rev1 -km default -e CONVERT_TO=proton_c
+```
+
+You can also add the same `CONVERT_TO=<target>` to your keymap's `rules.mk`, which will accomplish the same thing.
+
+?> If you get errors about `PORTB/DDRB`, etc not being defined, so you'll need to convert the keyboard's code to use the [GPIO Controls](gpio_control.md) that will work for both ARM and AVR. This shouldn't affect the AVR builds at all.
+
+### Conditional Configuration
+
+Once a converter is enabled, it exposes the `CONVERT_TO_<target_uppercase>` flag that you can use in your code with `#ifdef`s, For example:
+
+```c
+#ifdef CONVERT_TO_PROTON_C
+ // Proton C code
+#else
+ // Pro Micro code
+#endif
+```
+
+## Pro Micro
+
+If a board currently supported in QMK uses a [Pro Micro](https://www.sparkfun.com/products/12640) (or compatible board), the supported alternative controllers are:
+
+| Device | Target |
+|------------------------------------------------------------------------|-------------------|
+| [Proton C](https://qmk.fm/proton-c/) | `proton_c` |
+| [Adafruit KB2040](https://learn.adafruit.com/adafruit-kb2040) | `kb2040` |
+| [SparkFun Pro Micro - RP2040](https://www.sparkfun.com/products/18288) | `promicro_rp2040` |
+
+Converter summary:
+
+| Target | Argument | `rules.mk` | Condition |
+|-------------------|---------------------------------|------------------------------|-------------------------------------|
+| `proton_c` | `-e CONVERT_TO=proton_c` | `CONVERT_TO=proton_c` | `#ifdef CONVERT_TO_PROTON_C` |
+| `kb2040` | `-e CONVERT_TO=kb2040` | `CONVERT_TO=kb2040` | `#ifdef CONVERT_TO_KB2040` |
+| `promicro_rp2040` | `-e CONVERT_TO=promicro_rp2040` | `CONVERT_TO=promicro_rp2040` | `#ifdef CONVERT_TO_PROMICRO_RP2040` |
+
+### Proton C :id=proton_c
+
+The Proton C only has one on-board LED (C13), and by default, the TXLED (D5) is mapped to it. If you want the RXLED (B0) mapped to it instead, add this like to your `config.h`:
+
+```c
+#define CONVERT_TO_PROTON_C_RXLED
+```
+
+The following defaults are based on what has been implemented for STM32 boards.
+
+| Feature | Notes |
+|----------------------------------------------|------------------------------------------------------------------------------------------------------------------|
+| [Audio](feature_audio.md) | Enabled |
+| [RGB Lighting](feature_rgblight.md) | Disabled |
+| [Backlight](feature_backlight.md) | Forces [task driven PWM](feature_backlight.md#software-pwm-driver) until ARM can provide automatic configuration |
+| USB Host (e.g. USB-USB converter) | Not supported (USB host code is AVR specific and is not currently supported on ARM) |
+| [Split keyboards](feature_split_keyboard.md) | Partial - heavily dependent on enabled features |
+
+### Adafruit KB2040 :id=kb2040
+
+The following defaults are based on what has been implemented for [RP2040](platformdev_rp2040.md) boards.
+
+| Feature | Notes |
+|----------------------------------------------|------------------------------------------------------------------------------------------------------------------|
+| [RGB Lighting](feature_rgblight.md) | Enabled via `PIO` vendor driver |
+| [Backlight](feature_backlight.md) | Forces [task driven PWM](feature_backlight.md#software-pwm-driver) until ARM can provide automatic configuration |
+| USB Host (e.g. USB-USB converter) | Not supported (USB host code is AVR specific and is not currently supported on ARM) |
+| [Split keyboards](feature_split_keyboard.md) | Partial via `PIO` vendor driver - heavily dependent on enabled features |
+
+### SparkFun Pro Micro - RP2040 :id=promicro_rp2040
+
+Currently identical to [Adafruit KB2040](#kb2040).

+# Proton C
+
+The Proton C is an Arm STM32F303xC based drop-in replacement for the Pro Micro.
+
+<img src="https://i.imgur.com/GdsN1Rdh.jpg" alt="Proton C" />
+
+#### Features
+
+* Through-hole mounted USB-C Port
+* 32-bit 72MHz Cortex-M4 processor (STM32F303CCT6)
+* I2C, SPI, PWM, DMA, DAC, USART, I2S
+* 23x 3.3V I/O Ports
+* 1x 5V output for WS2812 LED chains
+* 256kB flash
+* 40kB RAM
+* AST1109MLTRQ speaker footprint
+* Reset button
+
+## Warnings
+
+Some of the PCBs compatible with Pro Micro have VCC (3.3V) and RAW (5V) pins connected (shorted) on the pcb. Using the Proton C will short 5V power from USB and regulated 3.3V which is connected directly to the MCU. Shorting those pins may damage the MCU on the Proton C.
+
+So far, it appears that this is only an issue on the Gherkin PCBs, but other PCBs may be affected in this way.
+
+In this case, you may want to not hook up the RAW pin at all.
+
+## Manual Conversion
+
+To use the Proton C natively, without having to specify `CONVERT_TO=proton_c`, you need to change the `MCU` line in `rules.mk`:
+
+```
+MCU = STM32F303
+BOARD = QMK_PROTON_C
+```
+
+Remove these variables if they exist:
+
+* `BOOTLOADER`
+* `EXTRA_FLAGS`
+
+Finally convert all pin assignments in `config.h` to the stm32 equivalents.
+
+| Pro Micro Left | Proton C Left | | Proton C Right | Pro Micro Right |
+|-----------|----------|-|----------|-----------|
+| `D3` | `A9` | | 5v | RAW (5v) |
+| `D2` | `A10` | | GND | GND |
+| GND | GND | | FLASH | RESET |
+| GND | GND | | 3.3v | VCC <sup>1</sup> |
+| `D1` | `B7` | | `A2` | `F4` |
+| `D0` | `B6` | | `A1` | `F5` |
+| `D4` | `B5` | | `A0` | `F6` |
+| `C6` | `B4` | | `B8` | `F7` |
+| `D7` | `B3` | | `B13` | `B1` |
+| `E6` | `B2` | | `B14` | `B3` |
+| `B4` | `B1` | | `B15` | `B2` |
+| `B5` | `B0` | | `B9` | `B6` |
+| `B0` (RX LED) | `C13` <sup>2</sup> | | `C13` <sup>2</sup> | `D5` (TX LED) |
+
+You can also make use of several new pins on the extended portion of the Proton C:
+
+| Left | | Right |
+|------|-|-------|
+| `A4`<sup>3</sup> | | `B10` |
+| `A5`<sup>4</sup> | | `B11` |
+| `A6` | | `B12` |
+| `A7` | | `A14`<sup>5</sup> (SWCLK) |
+| `A8` | | `A13`<sup>5</sup> (SWDIO) |
+| `A15` | | RESET<sup>6</sup> |
+
+Notes:
+
+1. On a Pro Micro VCC can be 3.3v or 5v.
+2. A Proton C only has one onboard LED, not two like a Pro Micro. The Pro Micro has an RX LED on `D5` and a TX LED on `B0`.
+3. `A4` is shared with the speaker.
+4. `A5` is shared with the speaker.
+5. `A13` and `A14` are used for hardware debugging (SWD). You can also use them for GPIO, but should use them last.
+6. Short RESET to 3.3v (pull high) to reboot the MCU. This does not enter bootloader mode like a Pro Micro, it only resets the MCU.

-# Converting a board to use the Proton C
-
-Since the Proton C is a drop-in replacement for a Pro Micro we've made it easy to use. This page documents a handy automated process for converting keyboards, as well as documenting the manual process if you'd like to make use of Proton C features that aren't available on Pro Micros.
-
-## Automatic Conversion
-
-If a board currently supported in QMK uses a Pro Micro (or compatible board) and you want to use the Proton C, you can generate the firmware by appending `CONVERT_TO_PROTON_C=yes` (or `CTPC=yes`) to your make argument, like this:
-
- make 40percentclub/mf68:default CTPC=yes
-
-You can add the same argument to your keymap's `rules.mk`, which will accomplish the same thing.
-
-This exposes the `CONVERT_TO_PROTON_C` flag that you can use in your code with `#ifdef`s, like this:
-
-```c
-#ifdef CONVERT_TO_PROTON_C
- // Proton C code
-#else
- // Pro Micro code
-#endif
-```
-
-If you get errors about `PORTB/DDRB`, etc not being defined, so you'll need to convert the keyboard's code to use the [GPIO Controls](gpio_control.md) that will work for both ARM and AVR. This shouldn't affect the AVR builds at all.

-The Proton C only has one on-board LED (C13), and by default, the TXLED (D5) is mapped to it. If you want the RXLED (B0) mapped to it instead, add this like to your `config.h`:
