Hello,

Anybody running on this chip? Any chance with a JTAG also?

Thanks.

Sorry, first I heard about it. Can you provide more information?

It it a new chip or a board?

It is the esp32 wroom module in a single chip.

All it needs are the antenna and its matching components.

m5stack now has some nice commercial units with this chip: https://m5stack.com/products/atom-matrix-esp32-development-kit and https://m5stack.com/products/atom-lite-esp32-development-kit

they are about 2cm by 2cm by 1.7cm and quite compact

just got mine in the mail, i was surprised how small it was

Features: WiFi, BT, Dual Core, 240MHz, Embedded Flash, VRef calibration in efuse,

240MHz - Cool this board will work with Espruino firmware build for ESP32.

looks like everything's in order. i'm unable to connect via web ide though, unlike my other esp32 boards. but connecting through screen is just fine.

preliminary testing of the neopixel in the atom lite (D27) works well (the pixel seems to be GBR)

the chip seems to be a bit warmer than i expected; it could be because the chip is running at the full 240mhz while being enclosed in plastic.

that's all the time i have to playing around for now, would probably pick this up again sometime later for a project :)

i forgot i haven't rebooted in a while on this machine and the issue with the espruino ide was most likely because my user wasn't part of the dialout group (but i probably added my user in the group in one of my persistent terminals, hence i was able to access via screen)

reboot solved all the issues :)
