Runs off a Trinket Pro, Ultimate GPS module and the two 24-channel PWM drivers. GPS digital clock test run. Note that dot matrix display is not active yet. Currently configured to show last few seconds before rollover of the minute, much like the beeps on the radio…
Clock logic is built on Arduino platform with LED chains being driven by Adafruit 24-channel PWM modules.
Adafruit Pro Trinket – 5V 16MHz: Trinket’s got a big sister in town – the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in, so delicious. (read more)

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.

The switch back and forth between Pro Trinket and Trinket Pro is disorienting. What should I be calling this glorious board? It says Pro Trinket on the PCB but then today alone there are two blog posts that call it Trinket Pro!
