It's almost certainly flash... I'm not sure anyone really uses OTP any more
The accelerometer is the tiny black thing on the opposite side of the chip to the crystal. I didn't check it was the kx022 yet, but I imagine it is.
I'm sure you could port Espruino to it, but it could be quite a lot of work. Generally it's not hard to get Espruino running with a serial terminal, but it'd take weeks to get it working with I2c, SPI, timers, etc, and then weeks more for Bluetooth :(
@Ducky damn, that's bad news. Can you post up a link to the different one? It'd be good if we could figure out if there was any obvious difference from the outside.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
@luwar wow, 50k? Sounds like an interesting chip.
