STATUS UPDATE: PICqueño32 v1.0

Posted on Tuesday, July 26th, 2011 in dev boards, Development, Status update by Ian

PICqueño32 is our knock-off the Arduino-compatible chipKIT Uno32.

Earlier this summer Microchip and Digilent released a 32bit, PIC 32 development board. Yeah, it’s in the shape of an Arduino. What sets it apart from others is the open source compiler that works with the Arduino IDE and existing Arduino programs.

We decided to make a chipKIT-compatible board to get a closer look at the platform. This is the first prototype and it will take some revisions to perfect the design. It’s going to be hard to compete with Digilent’s $27 price, but we might make a batch eventually.

PICqueño32 has the same basic circuit as the ChipKIT Uno, but we used our own partlist and made it way more dangerous:

  • Arduino shield form factor, works with most existing shields
  • Bigger, human-friendly FT232 USB->serial chip
  • Stripped-down power supply design
  • Designed entirely within the free version of Eagle
  • ChipKIT-compatible header placement
  • CC-0 from-scratch remake (CC BY-SA during development)

The original design has a fairly complicated power setup, so we simplified it to something easier for ordinary hackers to reuse in a project. USB or external power are toggled by a jumper. That will probably be an auto-select in the final design.

A build video will go up in a minute.

Schematic and PCB are on the PICqueno32 v1 wiki.

    so, only two layers? Does it work OK? There’s been some suggestions (in conjunction with some ARM-based Arduino-like designs) that two layers was not going to be sufficient for the higher speed CPUs…
