Rowetel’s SM2000 VHF radio PCB is developing nicely – he’s also requesting any help with software for the STM32F4 if you’re so inclined.
Since the last post in this series Rick, KA8BMA, has been working steadily on the CAD work for the SM2000 VHF Radio. We now have the SM2000 schematic and 80% of the PCB layout is complete. Rick has taken a modular approach, laying out each building block that I prototyped last year.
Here is the current state of the PCB layout, which is 160mm x 160mm
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
