Introducing the TinyPICO

Post by mattyt » Mon Mar 18, 2019 3:01 am

Hi folks,

Way back in September I posted that Seon (@seonr) and I had begun development on a small ESP32 board that was breadboard - and MicroPython! - friendly.

The design has been improved and refined over a number of revisions - in no small part due to the excellent feedback we received from this community - and we recently decided to create a Crowd Supply campaign. The TinyPICO Coming Soon page has just gone live!

We tried to incorporate the more interesting features you could want in such a board: USB serial, 4MB PSRAM, an onboard APA102, LiPo battery management, a reasonable number of GPIOs, a 3D antenna with good WiFi characteristics and a decent regulator. At 18x32mm we've been able to keep it small.

To those that provided feedback, thank-you! The TinyPICO is better for your input. Please do register at Crowd Supply if you're interested but I'll also post when the campaign goes live.

Cheers,
Matt (and Seon)

Looks very good.

You should put a 20 cent piece next to the board for people to reference the size.

Don't know which currency you're talking about, but just putting a ruler next to it is going to be clearer :D (ok, still a couple of possibilities, but more people are goig to know those)

Congratulation you guys ! This is looking really good. Registered for the sale...

One suggestion on a photo: how about a top-down photo showing the module plugged into a breadboard? perhaps better than a country-specific coin for trying to illustrate the compact module size?

Is it possible to release a schematic? I'm curious about:
- switching out the serial-USB converter during battery power
- auto-reset cct for integration with esptool
- V regulator used

I like the GND pins on both sides and the top layer ground plane that is visible in the photos.

Thanks Mike :-)

The project will be going open source once the campaign starts up, so you'll be able to see all the guts, glory and well... some of my whacky decisions ;)

I pic on a breadboard is a great idea, thanks!

I've not had a chance to take a breadboard shot yet, but here is a shot of TinyPICO next to some other popular ESP based dev boards...

Also, we launched our new TinyPICO website!
