Elite-Pi Usage Guide
The Elite-Pi is an RP2040-based controller with a Pro Micro/Elite-C compatible pinout that's primarily intended for use with keyboards.
In comparison to the Pro Micro or Elite-C, the Elite-Pi provides a few advantages over them:
- Flash memory: Lots of space to compile in various QMK features without worry, as the Elite-Pi has much more flash memory
- Price: Since the RP2040 microcontroller costs less than the ATmega32u4, we can provide it at a lower price than the Elite-C
- Flashing: Instead of using QMK Toolbox, you can just copy a complied
.uf2file to the Elite-Pi to update the firmware
The recommended way to use the Elite-Pi is using a converter in QMK. Note that you will not be able to take a
.hexfile compiled for a Pro Micro (ATmega32u4) and rename it as a
.uf2file, it just doesn't work that way. In either usage case, you will need a QMK build environment setup.
Using QMK CLI:
qmk flash -c -kb keebio/levinson/rev3 -km default -e CONVERT_TO=elite_pi
make keebio/levinson/rev3:default CONVERT_TO=elite_pi
At the moment with V1 of the Elite-Pi, there are two buttons on it for
Boot, unlike the Elite-C, where there is only one button needed for
Reset. The left button is for
Boot, and the right button is for
Run. You will mainly be interested in getting the Elite-Pi into bootloader mode, so please see the directions below for doing this.
In the future, we plan on reducing the Elite-Pi to have just one button to perform
To repeat the information there, here's the steps:
- 1.Enter bootloader mode (use one of the following methods):
- For a new Elite-Pi out of the packaging, it will already start in bootloader mode when plugged into the computer
- Hold the
Bootbutton (the left button) down, press the
Runbutton (the right button), and release both buttons
- Hold the
Bootbutton (the left button) down, while pluging in the USB-C cable
- Press the
QK_BOOTkeycode (if present on a flashed keyboard)
- 2.Wait for OS to detect the Elite-Pi
- It will show up as a USB mass-storage device named
- 3.Copy the
.uf2file to the
If you have the Elite-Pi installed with the back facing towards you, and you need to press
Boot, take a wire and connect the
Bootpad on the back and a
GNDpad, as shown below:
No, you can not mix the Elite-Pi with a non-RP2040 controller like the Pro Micro or Elite-C.
However, another RP2040 controller can be used with it.
If you would like to access D10 and/or D11 via the pads on the side of the Elite-Pi, you will need to cut the traces connecting GND to the those pads, as by default, the side pads are connected to GND to match the normal Pro Micro pinout. After cutting the traces, add solder as shown below to jump D10/D11.
