There are two versions of STeMCell available, with different pinouts:
- v1.0.0
- v2.0.0 (pre-release v1.0.1, v1.0.2)
Default official firmware only supports v2.0.0 STeMCell.
STeMCell has support to swap UART and I2C pins, to enable single-wire uart communication in STM chips.
The following additional flags has to be used while compiling, based on the pin used for split communication.
| Split Pin | Compile flags |
|-----------|---------------|
| D3 | -e STMC_US=yes|
| D2 | Not needed |
| D1 | -e STMC_IS=yes|
| D0 | Not needed |
