[REQUEST] EmberZNet Zigbee NCP and OpenThread RCP firmware for "Arduino Nano Matter" development board with USB is based on Silabs MGM240S module (containing Silicon Labs EFR32MG24 SoC)?

[Hedda]

Spotted at cnx-software.com tech blog and thought it might be a nice MGM240S hardware board for prototype testing, etc.

"Arduino Nano Matter" development board with USB is based on MGM240S module (containing Silicon Labs EFR32MG24 SoC)

Any chance we could get EmberZNet Zigbee NCP and OpenThread RCP firmware builds for this MGM240S based board?

Similar to MGM240P based Sparkfun Things Plus Matter board so guess requires a Gecko bootloader to be flashed first? -> https://github.com/darkxst/silabs-firmware-builder/pull/31

Yes should be able to add this, once I get my hands on one. I would expect it also needs bootloader installed first.

• IEEE 802.15.4 Radio Transmit Output Power (dBm) = 10
• Antenna = 2.4GHz Ceramic Chip Antenna surface mounted component on-board

When comparing the main hardware pros and cons with these two boards are the Transmit Output Power and Antennas used:

Arduino Nano Matter pros and cons:

• Arduino Nano Matter - Pros = Ceramic Chip Antenna (usually offers better performance than a PCB Trace antenna)
• Arduino Nano Matter - Cons = Based on MGM240S which only offers +10 dBm TX Power (however that should work good)

Sparkfun Things Plus Matter pros and cons:

• Sparkfun Things Plus Matter - Pros = Based on MGM240P which offers +20 dBm TX Power
• Sparkfun Things Plus Matter - Cons = PCB Trace antenna (usually offers worse performance than Ceramic Chip Antenna)

PS: If want to test external u.fl antenna see the official xG24-RB4187C (BRD4187C) and xG24-RB4186C (BRD4186C) radio boards.

• xG24-RB4187C (BRD4187C) based on the same SoC as MGM240P

I will note that the Sparkfun board has a full blown j-link debugger integrated. This should be superior to the debugger on the Arduino board, particularly if developing with Simplicity studio.

Also re power, for use as a Thread RCP TX power should be limited (probably < 10dBm) to avoid asynchronous power levels

Zigbee Coordinator also works better if limited to around 10 dBm, because otherwise it can transmit messages directly to Zigbee devices far away but those devices might have a harder time to transmit back messages.

€21 (21 Euro) as recommended retail price in the European Union for this MGM240S based Arduino Nano Matter is not bad at all.

Compared to the MGM240P based Sparkfun Things Matter which cost $24,95 US in the United States but much more in the EU.

(Not as high price for it in the United Kingdom though https://thepihut.com/products/sparkfun-thing-plus-matter-mgm240p)

I got this today, so far not looking good for firmware:

• Only seems to have CMSIS-DAP debug interface and no UART pass-through for the MGM240 chip
• Only works with Arduino IDE (or openOCD), doesnt seem to be supported by any of the Silabs tools Simplicity Studio or Commander.

So it seems primarily intended for use with Silicon Labs Arduino Core + Arduino IDE only.
