+# 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.

+
+![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.
