We use the cp2104 usb-serial converter in a lot of our designs – but it’s hard to get during the shortage(s). The cp2102n is available, and it’s a clooooose replacement but theres a few small hardware changes needed and the internal eeprom is different. So, if you just spent 2 days trying to figure out why your cp2104 eeprom writing code isnt working and you were dreading having to rewrite the libusb vendor calls, good news! This pr to a fork of a program compiled cleanly and did the job a treat on our raspberry pi tester. https://github.com/irrwisch1/cp210x-cfg/pull/1 whew 🙂 – video.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
