About the HamWing PCB

HamWing is an open source PCB design by W8LID, published on GitHub under the SHL-2.1 license. It is a 2-layer board measuring 50.8 × 71.1 mm, with 27 components from 19 distinct parts.

Other key parts include the DRA818V, DRA818U and LM4810. By type, the board carries 10 capacitors, 6 inductors, 5 resistors, 3 ICs and 3 connectors.

It belongs with the dev boards & breakouts, audio and displays & leds designs in this gallery.

From the project

A carrier board for Dorji DRA818V/U modules that is compatible with Adafruit Feather development boards.

The HamWing FeatherWing allows you to create a fully functional VHF/UHF transceiver using the Adafruit Feather platform. It has the same physical dimensions as the Feather Tripler making it easy to add a microcontroller as well as other FeatherWings like an OLED for a display. The modules are powered via the BAT pin to allow use with a LiPo pack connected to the Feather used for control. The HamWing was designed around the use of an Adafruit Feather M0 but should be compatible with other Feathers as well. We will list other compatible boards as they are verified to work.
