Raspberry Pi Zero W

Technical Specifications

The Raspberry Pi Zero features a BCM2835 chipset, overclocked to 1Ghz with 512MB RAM, and the same 1080p video output, so there’s plenty of oomph in that little board. It also features the same 40 pin GPIO layout as the Raspberry Pi 2/B+/A+, which you’ll need to solder your own headers too. With its small form factor and reduction in connectors, the Raspberry Pi Zero only uses ~ 140mA at 5V!

Unlike it’s larger brothers and sisters, the Raspberry Pi Zero has an unpopulated GPIO, unpopulated composite (RCA) header and an unpopulated reset header. There’s also no DSI screen port, no ethernet, no analog audio, and no full-sized USB ports. Instead, the Pi Zero features a micro-USB power port, a micro USB OTG host port (for peripherals e.g. WiFi dongle), and a mini HDMI port for video.

HAT Compatibility Note: The Pi Zero is fully compatible with all HAT breakout boards, as it features the same 40 Pin GPIO as the Raspberry Pi 2/B+/A+

How to use a Raspberry PI as a radio transmitter with Rpitx

Using Rpitx software from F5OEO, a raspberry PI can be used to transmit radio signals from 5khz to 500Mhz (AM/FM/SSB/FSQ/SSTV), using the GPIO 18 extension (pin 12) to connect a wire to serve as an antenna. The length of the wire depends on the frequency used to transmit.

Note that the generated signal is not “clean” and generates many harmonics that are harmful if amplified, without filtering.

With the addition of an RTL-SDR USB stick for reception, it’s then possible, as an experiment, to create a transceiver with the qtcsdr software from HA7ILM.

As with any radio transmission equipment, the use is subject to the respect by the user of the laws in force in the country of use.
