Hello,

Our internal pads are marked, and this information can be seen in photo that you attached too, however there is no TX RX pins in TRB142 7x2 header.

Pinout would be as follows:

SPI_CS_N ADC
SPI_MOSI GPIO_12
SPI_MISO GPIO_14
SPI_CLK GPIO_15
I2C_SCL GPIO_38
I2C_SDA GPIO_26
3V8 GND


There is UART connection on the other side of PCB though, where pinout would be:

RX TX
- HW_RST
- GND
- -
- -
- 3V3
1V8 3V8

Marking is also on PCB itself.

Best regards,
Vidas.
