Vipr
About the Vipr PCB
Vipr is an open source PCB design by goog-yaml, published on GitHub under the MIT license. It is a 2-layer board measuring 30 × 65 mm, with 37 components from 24 distinct parts.
Other key parts include the SX1262IMLTRT, TP4056-42-ESOP8, BGS12P2L, MIC5219-3.3YMM and CH340X. By type, the board carries 16 capacitors, 7 resistors, 5 ICs, 3 connectors, 2 diodes and 2 inductors.
It belongs with the rf & radio, dev boards & breakouts and usb & debug tools designs in this gallery.
From the project
VIPR is a open source radio node designed and built around North American mesh communication over LoRa built off of an ESP32-S3 platform. Put less simply, VIPR is another ESP32 development board focused more on frontend, hardware, and size.
Simply put, VIPR is a open source radio node designed and built around North American mesh communication over LoRa built off of an ESP32-S3 platform. Put less simply, VIPR is another ESP32 development board focused more on frontend, hardware, and size. The project aims to create a small, pocketable radio node that can run independently. Currently the procsessing power of it's latest version (2.0) can only handle small workloads and can only run a Real Time OS in comparison to a fully fledged computer.
