micro-ROS strikes again!
We have further enlarged the family of supported boards, by porting the small turtle to the ESP32-S2. This MCU is a highly integrated Wi-Fi SoC endowed with a rich set of peripherals and I/O capabilities, designed for high-performance ultra-low-power applications.
The ESP-S2 features a high performance single-core (up to 240 MHz), 128 KB of ROM, 320 KB of SRAM plus an embedded flash depending on the specific board version.
As a welcome addition, we mention that the ultra-low power consumption mode in this chip has been recently investigated by @MS71. This resulted in an example app configured so as to cut down the consumption to a mean current of ~ 5 mA when minimizing the wireless communications, corresponding to a lot of micro-ROS working hours on batteries.
