CC2530PA Notes
CC2530PA from banggood's connections:
| RFX2401C | CC2530 |
|---|---|
| TXEN | P1_5 |
| RXEN | P1_4 |
I modified the z-stack zigbee firmware to have TXEN on PA1_5 and RXEN on P1_4 and improved RF performance over the stock CC2530_CC2592 firmware, and seemed to be better than the CC2531 USB stick I have
