PtSolar-Breakout
About the PtSolar-Breakout
PtSolar-Breakout is an open source PCB design by custom-ds, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 24.5 × 73.5 mm, with 18 components from 15 distinct parts.
Other key parts include the LM1086-5.0 and BME280. By type, the board carries 6 connectors, 5 capacitors, 2 ICs, 1 transistor, 1 switch and 1 diode.
It belongs with the dev boards & breakouts, power & battery and sensors designs in this gallery.
From the project
Under the hood, the ptSolar runs on the same Microchip ATMega328p microcontroller that the other trackers have been using for years, although this board runs at a lower 3.3 volt level, and a slower 8MHz clock speed.

A 2m VHF transmitter is provided by the SA818S-V transmitter-on-a-chip system, which means it's frequency agile and can be used throughout the world.
