ESP32-C3

Not sure it has already been announced here so...

Looks like a new RISC-V buddy is coming: https://www.espressif.com/en/news/ESP32_C3

That's a fairly predictable direction for them to go in, but it seems very confusing to call it the ESP32.

Note that they have also recently released the ESP32-S3,  based on an Xtensa LX7 core. The ESP32 series was initially only based on Xtensa cores, but I don't think that was set in stone in the ESP32 name. ESP32 was not the name of the underlying architecture.

Looks like now the naming will be ESP32-S for Xtensa-based MCUs, and ESP32-C for RISC-V-based ones.

And that said, the latest ESP32-S3 looks like quite a beast and is much more powerful (in terms of processing power) than the -C3. It will be interesting to see what the pricing is.

Let's all pray for a decent ADC.

Let's all pray for a decent ADC.

From the DS, it embeds two 12-bit, 2 Msps SAR ADCs, with the following characteristics:
DNL = +/- 7 LSB
INL = +/- 12 LSB

I don't know how that compares to the older ESP32.

The new chip interests me for sure.

We use the ESP32 original in our current products and the biggest issue we have with it is low power support in BLE and in WiFi AP mode.
Part of this i think stems from the original chip supporting Standard BT as well as BLE.

From what i can see/understand/infer the new chip only supports BLE?
So hopefully at least the power consumption with only BLE running will be lower.

Quite useful for our development in that this new chip will be supported by their current development framework, so should make it much easier to port our code across to this new product.
As well as them offering the chip in a module with the same footprint as their current modules.
