Poll: Are you interested in roadtesting an energy-efficient ultra-low power MCU Eval Board?

I was contacted by Renesas who would like their MCU board roadtested. I'd like to get your interest in roadtesting it.

Here's a description:

RA2L1 MCU Evaluation kit enables users to evaluate the features of the RA2L1 MCU group and develop embedded systems applications using Flexible Software Package (FSP) and e2 studio IDE. It features R7FA2L1AB2DFP MCU (referred to as RA MCU) with 48MHz, Arm Cortex-M23 core, 256KB code flash, 32KB SRAM in 100 pins LQFP package. It has multiple clock sources (low-precision clocks are available internal to the RA MCU). Additionally, RA MCU oscillator and sub-clock oscillator crystals, 20.000MHz and 32,768Hz are provided for precision. The board feature three user LEDs (red, blue, green), power LED (white) indicating availability of regulated power, debug LED (yellow) indicating the debug connection, two user buttons and one reset button.

Here's some features:

Native pin access through 1 x 40-pin and 3 x 20-pin male header
MCU current measurement points for precision current consumption measurement
Internal MCU DC-DC power option
Two 5 V input sources (USB (debug), external power supply)
Three debug modes (debug on-board (SWD), debug in (ETM, SWD, and JTAG), debug out (SWD))
2 seeed Grove system (I2C/analogue) connector
SparkFun Qwiic connector, 2 Digilent Pmod (SPI and UART) connectors
Board dimension is 80mm (width) x 140mm (length)
Arduino(Uno R3) connector, MikroElektronika mikroBUS connector
MCU boot configuration jumper

It is interesting to see M23 core. M23 was first Cortex-M of the new generation of Cortex-M cores (with ARM v8-M instruction set. All previous cores are v7 or even v6 in case of Cortex-M0). For some reason most vendors skipped this core and only produces MCUs with M33.

Interesting to see Renesas making an ARM Cortex M23 product. I hadn't been following their ARM offerings, but they have a whole family of them.

The board is his arm for which is pretty good in terms of compatibility. However I have not heard of any cortex M 23 cores before.
There are a lot of connector standards on the board which should in theory allow for good Prototyping usage for the evaluation of the chipset.
I will go study the board and see if it has any code examples for prototyping and also check out the development suite.

You don't often come across an Arm Cortex-M23 dev board. The last one I came across was one I roadtested some time back, namely the Microchip SAML10 Xplained Pro Evaluation kit.

This will make for an interesting comparison.
