About the WifiRc PCB

WifiRc is an open source PCB design by jenschr, published on GitHub. It is a 2-layer board measuring 49.8 × 68.5 mm, with 38 components from 21 distinct parts.

Other key parts include the WM-N-BM-14, AMS1117 3.3V, L9110 and AMS1117 5.0V. By type, the board carries 11 capacitors, 8 resistors, 6 ICs, 3 modules, 3 connectors and 1 LED.

It belongs with the robotics & motion designs in this gallery.

From the project

Can run off USB (no motor) or 7.4 or 11.1V batteries (depending on what your motors need). Set your power source using the VS jumper. The 5V outputs are intended to dirve Servo's, but the wiring isn't exactly ideal. A new version may set aside 3 pins for dedicated Servo outputs.

The module has been produced and tested, but not yet mounted in a model. See pictures of the reflowed and soldered board here and a short video from testing here.
