PCB for Wemos D1 + Nokia5110-display + nRF24L01+

Simple pcb to plug a nRF24L01+ together with a Wemos D1 Mini / Pro and a NOKIA5110-display (known as PCD8544). One goal : You can power this pcb via USB-interface of D1-mini.

attached zip was created with easyeda. You can order easyly on jlcpcb.com.

Attention

Be sure you have the right type of nokia-display-pcb ! Check pin-header-description (There are different versions avail)! ( check picture : LIGHT (or BL) is placed between GND and VCC )

A picture of earlier version of pcb.

D1-mini and NRF placed on front side, nokia display will soldered bottom. You can use this PCB also without mounting a Nokia-display.

Actual version of PCB has mounting holes and additional 5V/Gnd -pin access.

SSD1306

Some changes made possible to use SSD1306 (instead of NOKIA5110 display). img

You can use same PCB. You only have to connect GND (SSD:GND), VCC (SSD:VCC), D/C (SSD:SDA) and SCE (SSD:SCL) img

On other PCB-layouts, PIN wemos:D1 need connected to SSD:SCL and wemos:D2 has to be connected to SSD:SDA. much fun.
