A campaign has been launched on Kickstarter for an RF breakout board for the Raspberry Pi.
The Raspberry Pi has been a huge hit with radio amateurs and other hobbyists since its launch in 2012.
Every Raspberry Pi has a programmable clock generator on board which can be used as a frequency synthesiser up to 250MHz with a logic level output capable of delivering 10mW without any amplification.
The Kickstarter kit provides a breakout board that brings the Raspberry Pi clock generator out to a BNC socket with a prototyping area for your own circuits. Building a QRP WSPR beacon is as simple as adding a low pass filter and downloading the Raspberry Pi WSPR software.
