Radio
About the Radio PCB
Radio is an open source PCB design by hedj, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 65 × 56 mm, with 89 components from 34 distinct parts.
Other key parts include the G144A12, NCP1117ST18T3G and NCP1117ST33T3G. By type, the board carries 8 capacitors, 3 ICs, 3 diodes, 2 LEDs, 2 inductors and 1 connector.
It belongs with the rf & radio designs in this gallery.
From the project
A minimal software-defined radio, based on the GreenArrays GA144A12 microprocessor. Provision is made for connection to a Raspberry Pi B+ and shields. The GA144 analog i/o pins are brought out to pin-headers to allow for different choices of RF frontends.
