This is an update to the existing Easy-Peasy Amplified MySensors Serial Gateway. I've added gateway traffic LEDs and an enclosure.

Like the original, it uses an nRF24l01+ module with a PA (Power Amplifier) and an LNA (Low Noise Amplifier).

Build Steps

1. Purchase Lolin D1 Mini
2. Purchase nRF24L01P+PA+LNA (Ebyte E01-ML01DP5)
3. Order and populate the Easy-Peasy-LEDsy NRF24 shield.
4. Print Easy-Peasy-LEDsy Enclosure.
5. Connect the 3 LEDs (3mm) to the shield (see schematic), allow 7 cm of wire length to reach cover.
6. Mount the LEDs to the cover.
7. Program the D1 mini (in Arudino IDE, select board: LOLIN(WEMOS) D1 R2 & mini) with the attached gateway program.
8. Place the D1 mini in the enclosure and fix it with the hold down and 2 M2 x 5 mm self tapping screws.
9. Assemble the shield and nRF24 module to the D1 mini.
10. Mount your LEDs to the cover and snap it on to the enclosure.
11. Plug the gateway into your controller via a USB cable.
12. Enjoy.

Notes:

• When using MySensors library 2.3.2, you must use ESP8266 core v2.6.2
• LED mapping: Rx - pin D0, Tx - pin D3, Err - pin D1 (attached code takes care of this)
• See MySensors Advanced Gateway Options for details about LEDs
• I use a small board with a pin header to mount the LEDs to the cover
