simpleSA
Simple Spectrum Analyser, based on 2 off SI4432 modules, an ADE25 mixer, a programmable attenuator and some filters. This version is intended for homebrew by those experienced in amateur radio or similar techniques, or those wishing to explore these and learn the hard way! No support is available for the code or the hardware.
The code was initially based on Arduino code for STM "Blue Pill" developed by Erik PD0EK and ported to run on an ESP32 by Dave M0WID.
Subsequently the code has been extensively reorganised, modified and developed, with much of the work done by John WA2FZW. Additional features have been added, including the ability to view the trace and change settings from web clients, and later additional modes such as signal generator, IFSweep and the ability to control a tracking generator.
Glenn VK3PE has developed some boards for this version - see his website.
Erik has since gone on to produce a commercial version called TinySA. The commercial version has quite a lot of additional features, but does not include the wifi features of this version, or the integrated tracking generator.
