Last week, I wrote about ESP32-PICO-D4 system-in-package (SiP) that contains ESP32 WiSoC, 4MP SPI flash, a crystal oscilloscator and some passive components in a single 7×7 mm package in order to allow smaller designs based on ESP32. The company noticed the post, and asked me whether I’d be interested in receiving “some development boards based on ESP32 PICO”, an offer hard to refuse :), and within a couple of days I received the package below.
There’s also an antenna, a EN and BOOT buttons, and a micro USB port. The board measures 52x20mm. On actual product, the USB bridge part would be there, so you could have something around half size or even much smaller…
… something like the ESP32-PICO-D4 module below whose picture I found on the web.
ESP32 Pico Core is clearly smaller. Compared to ESP32-T it’s about the same length, but much thinner, and include 2 extra pins, while in terms on functionality it’s more comparable to ESPino32 both with 40-pins, two button, and micro USB port, but the size difference is even greater.
If you wonder, the board is breadboard compatible, and since it’s thinner leave two rows of pins free on each side, compared to just one for most boards.
The boards are not for sale right now, and there’s no info on their website about them. You’ll however find some more details in ESP32-PICO-D4 datasheet.
