This shield is designed for easy powering and using four GPIOs of ESP-01/01S module. It is powered by 5 volts DC and has four 3-pin screw terminals for connecting some periphery like 2812 LEDs, relay modules, etc.
same board as rev_3, with new layout and smaler PCB
- LDO changed to AP7361C-33ER SOT-223 (1117-3.3 compatible pinout)
- ESP-01/12 changed to ESP-Goofy (look for TheGoofy 2019 Adapter)
- small improvements
- silkscreen fixed
original designed in EAGLE
- board and schematic attached
PCB will be tested next days, before going in production
This is a programmer of the module ESP-01 or ESP-01S with converter usb-ttl (its in the image). When Switch Prg is short, ESP-01 is on programmer mode, you must reset the module with Rst switch, this way the usb serial will be recognized.
Besides this PCB is thinked for use with the antena NRF24L01, on the pads P1..P8.
(Coming soon done!).
