Understanding the GPIO pin out mapping for CC2540DK (SmartRF05EB + CC2540EM module)

Developing a prototype with the CC2540DK (SmartRF05EB + CC2540EM) I hit the issue where the pin mapping from the CC2540 chip to the final breakout pin headers is extremely convoluted. Here is source of this issue: CC2540 is mounted on the CC2540EM module using Pin headers P1 and P2. This implies one pin mapping from […]
