# 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 )
![img](Nokia5110-LCD.jpg) or ![img](Nokia5110-LCD2.jpg)
---
A picture of earlier version of pcb.
![img](PCB-V1.jpg)
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.
## after soldering ...
![img](1_Front.jpg)
NRF & Wemos on Front
![img](2_Bottom.jpg)
Nokia Display soldered on bottom side
![img](3_booting.jpg)
while booting (wait for wifi, 1st data, ...)
![img](4_runIP.jpg)
1st screen show most interesting info and IP in bottom line
![img](5_runTime.jpg)
this is the normal screen with time in bottom line (refresh all 5 seconds)
# SSD1306
Some changes made possible to use SSD1306 (instead of NOKIA5110 display).
![img](SSD1306.png)
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](6_Wiring_SSD1306.png)
On other PCB-layouts, PIN wemos:D1 need connected to SSD:SCL and wemos:D2 has to be connected to SSD:SDA.
much fun.
