#Bill of Materials DIY STM32 Module 

Here is the bill of materials for the STM32 version of the DIY  MPTM. There are three versions. Carefully compare your board with the pictures below to determine which version you have. 

All diagrams and eagle files are available [here](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/tree/master/STM32%20PCB)

If you are looking for the BOM for the DIY ATmega328 3.2d version click [here](BOM_DIY_ATmega.md).

Digikey may not be your preferred supplier, but you should find enough information on their page to cross reference parts.

## IMPORTANT NOTE on Telemetry
In the case of the Turnigy 9X/9XR/9XR Pro you don't need to invert the telemetry signal therefore the instalation of the inverter chip SN74LVC2G86DCTR is  **OPTIONAL**. In this case and in order to have telemetry you need to solder **SJ1/SJ301** on the back of the board depending on which board version you have.

The inverted telemetry signal is required by TARANIS TX and other boards so for telemetry to work properly the inverter chip must be installed.

## BOM DIY STM32 PCB V1.0t - the USB version
This BOM is for the board with the USB port which allows firmware upload.

The board is available at OSHpark [here](https://oshpark.com/shared_projects/GX51nEoH)
