Andrews & Arnold Ltd are a UK based communications company. We sell internet, telephone, SMS, and make some serious routers (FireBrick). We use a lot of open source, and give back with a lot of open source code and hardware designs on Codeberg. We have many open source PCB designs. These are not sold as consumer products, but assembled PCBs, development boards for hobbyist use. Suggestions and git merge requests on Codeberg always welcome. https://lectronz.com/stores/revk Custom RSS Generator https://lectronz-images.b-cdn.net/lectronz/active_storage/representations/proxy/eyJfcmFpbHMiOnsiZGF0YSI6MjkwMTEsInB1ciI6ImJsb2JfaWQifX0=--32e1a1408df763d3056ec3c5b4d09f16631d385e/eyJfcmFpbHMiOnsiZGF0YSI6eyJmb3JtYXQiOiJwbmciLCJyZXNpemVfdG9fbGltaXQiOlsxOTIsMTkyXSwic2F2ZXIiOnsic3RyaXAiOnRydWV9fSwicHVyIjoidmFyaWF0aW9uIn19--0808b744be7c555ce58430d0ed7115f4f35a0403/aac.png https://lectronz.com/stores/revk Genuine Waveshare 7.5" laminated glass e-paper panel (mono), black border, RAW PANEL (needs controller) Fri, 01 May 2026 12:47:44 +0000 https://lectronz.com/products/waveshare-75-glass-laminated-epd-black-border https://lectronz.com/products/1738 ESP32-S3-MINI-1-N4-R2, USB-C, TDK ICS 43434 microphone, 124 WS2812 style LEDs in rings, diffuse case, works with WLED, with Stargate print Fri, 01 May 2026 12:47:54 +0000 https://lectronz.com/products/led-sound-reactive-printed-coaster-dev-board https://lectronz.com/products/1733
