Board definitions are available for the Atmega328p, STM32, and OrangeRX modules. The board definitions make it easier to compile and install the multiprotocol module firmware.
Note: The Orange RX module is now included in the Multi 4-in-1 AVR Boards package, it no longer has a dedicated package. If you have the dedicated OrangeRX package installed you should remove it and install the most recent AVR package (v1.0.2 or newer).
The board definitions are installed using the Arduino IDE Boards Manager.

Click OK to save the change
-
Click Tools -> Board -> Boards Manager
-
Type multi into the search box to see the Multi 4-in-1 boards
-
Click on the board you require and click the Install button. Repeat for both boards, if required. If you are installing the STM32 board for the first time, and you have not installed any STM32 or SAMD boards before (such as Arduino Due or Zero) the dependency toolchain will also be downloaded and installed.
-
Click Close to close the Boards Manager
-
Click Tools -> Board
-
Scroll down the list to the Multi 4-in-1 board headings verify that the boards you installed are available:
- Multi 4-in-1 (STM32F103CB) for the STM32 module
- Multi 4-in-1 (Atmega328p, 3.3V, 16MHz) for the Atmega module
- Multi 4-in-1 (OrangeRX) for the OrangeRX module
Refer to the hardware-specific pages for information on compiling the firmware and uploading it to the multiprotocol module:
