Hey folks, 

Got a small special update today. This is actually old news but I realized I didn't post about it yet. At the moment I am still working on the madre/mothership/basestation hardware based on the Beaglebone but before I started that I banged out one of the wireless sensor boards.

Introducing SunLeaf S1G:

There it is version 1 completely finished and ready for fabrication!! It has the following hardware features:

- ST Microelectronics SPSGRF-915 Spirit 1 Chip Module for S1G coms

- ST Microelectronics STM32F446RET6 ARM Cortex M4 180MHZ MCU
- BQ240210 Lithium Ion Solar/USB charge controller and battery management 
- 500mA Lithium Polymer battery with thermistor 
- I2C ports QWIIC connectors
- UART ports QWIIC connectors

This piece of hardware will be used for developing all the long range outdoor sensors in the Agricoltura IO platform, a modified version will be developed for indoor wireless later on. This board will be running a modfified version of the original SunLeaf firmware, retooled to use the Spirit-1 module for wireless coms instead of the ESP8266 that the original used. 

Thats all for now, I best get back to layout and firmware development as the clock is tickin!
