3.5 Test GPIOs for 8266 Dongle
Since all GPIOs of Telink TLSR8266 debugging dongle board are already
connected to corresponding pins of headers including J4, J18, J21 and J22, user can
directly test GPIO signals on header pins.
Note:
Only J4 and J20 are soldered on 8266 debugging dongle demo board supplied by
Telink. User needs to solder J18, J21 and J22 for development purpose.
