About the Panel PCB

Panel is an open source PCB design by timshac, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 75.5 × 72.7 mm, with 14 components from 12 distinct parts.

Other key parts include the ARGON, SP3485CN-L and Pololu_Reg16a. By type, the board carries 5 connectors, 3 ICs, 2 diodes, 2 capacitors and 2 resistors.

It belongs with the dev boards & breakouts and iot & wireless designs in this gallery.

From the project

RS-485 FeatherWing for Feather style microcontrollers. Instant Mobile App possible with Particle.io ecosystem

Can be used with any Feather style microcontroller

Firmware and simple mobile app available for Particle Argon or Boron microcontroller.
