The first SPINES Mote design features a solar-powered ESP8266 (admittedly, powering a power-hungry Wi-Fi radio with a tiny solar cell might not be the best idea; a LoRa version is coming soon) with three onboard environmental sensors:

• BME280 for temperature, humidity, and pressure
• CCS811 for volatile organic compounds (VOCs)
• VEML6075 for UVA and UVB light

The first batch of PCBs is now being fabricated on PCBWay's factory floor. While waiting for the PCBs and parts to arrive early next week, I will introduce the modular design of SPINES in the next couple of days.
