Created by Wijnand on 2018-04-26 12:58:11

2 Layer Board - 2.6680 sq in (0.9200in x 2.9000in) / 1721.29 sq/mm (23.37mm x 73.66mm)
$10.38 per set of 4 ($3.89 per sq in)

This design (a RFM95W controlled by an Arduino Pro Mini) is my first step in the world of IoT. The board is tested with raw.ino from the Matthijs Kooijman LMIC library (https://github.com/matthijskooijman/arduino-lmic) and works fine.

A second PCB design is planned as sensor/power supply board as piggyback for the iot_lora. Power alternatives will be: solar cell, CR2032, 2 x AAA, Supercap, TPS61291, TPL5111 and/or TPS22860.

ATTENTION:The update to V2.0: ADC6 and ADC7 (analog exclusivily) are not connected to JP3 anymore but PB0 and PB1 (possibility for soft serial). The HF part has now a switch to SMA or spring antenna and added are GND planes on both sides.

BOM
1 x RFM95w/868MHz
1 x Arduino Pro mini
2 x 10K (R1, R2 for I2C pull up's)
