about the supply voltage range. the main issue is not with ESP32, but with the flash chips which usually runs off 3.3V, with the exception of some vendors which went as low as 2.2V. with ESP32, we decided to try using 1.8V flash; hence we can now go to 2.0V.

nope. only internal reference. The DAC is reference to same voltage as the ADC.

The reason for this is a design change in ESP31B in the crystal oscillator to radically reduce the power consumption (during sleep), and add more tuning range to the crystal oscillator. This resulted in the crystal being sensitive to the type and brand of crystal used and somehow even the design of ...

yes, the ROM is very rudimentary; we are in the process of defining the ROM now, including SSL functions, and especially those functions related to security.

yes, i think this is a splendid idea. Will get management to look into this.

sorry guys, we ran out of boards and chips. there is another batch coming. but this one will take a while.

103mA doesn't seem the kind of number that we are expecting during boot. we need to check on this...

the pin outs are now available at

Thanks to Pighixxx!

the first few versions of the SDK comes without Bluetooth. we will try to enable it ASAP. probably within 3 months. we try not to be too buggy.

it's under consideration. we are doing SMT, but it's still not at the level that we would like it to be. Hardware takes a while to iron out the wrinkles... thanks.
