1 year ago FYI, I asked ITead was got the reply that the pinout definition for the EFR32MG21 SoC chip on the new model ZBDongle-E board is the same as the original first-generation barebone Zigbee 3.0 USB Dongle model 9888010100045, but they answered that the new model ZBDongle-E adapter can still not use the exact same firmware images as their old barebone model 9888010100045 adapter, so I guess that must mean that they do not use the exact same EFR32MG21 SoC chip model or?
https://github.com/xsp1989/zigbeeFirmware/blob/master/firmware/Zigbee3.0_Dongle/EZSP/README.md
I also asked ITead about the default RF output power configuration and was told that the new ZBDongle-E adapter currently ships with Zigbee NCP 6.10.3 firmware that has enabled 20 dBm output RF power default, however is not hardcoded in the firmware so users/applications can choose to lower output RF power if they want.
In addition, got part of Configuration Parameter values Table for Silicon Labs EmberZNet PRO Zigbee networking protocol stack:
| Configuration Parameter | Value |
|---|---|
| EMBER_APS_UNICAST_MESSAGE_COUNT | 32 |
| EMBER_PACKET_BUFFER_COUNT | 250 |
| EMBER_NEIGHBOR_TABLE_SIZE | 26 |
| EMBER_SOURCE_ROUTE_TABLE_SIZE | 200 |
| EMBER_ADDRESS_TABLE_SIZE | 32 |
It does not mention "Child Table Size" but I guess that is probably configured to 32 same as for old model 9888010100045 as per https://github.com/xsp1989/zigbeeFirmware/blob/master/firmware/Zigbee3.0_Dongle/EZSP/README.md or?
PS: The "ZBDongle-E" USB "product description id" has also "SONOFF Zigbee 3.0 USB Dongle Plus V2" written to EEPROM of WCH CH9102F USB-to-UART bridge on the board to enable auto-discovered of the USB-adapter for ZHA integration in Home Assistant.

@xsp1989 Can you tell if existing firmware releases are compatible with ITead's new “ZBDongle-E” that is also based on EFR32MG21?

I guess my question is if it this new “ZBDongle-E” dongle board is pin-compatible with the first/old ITead bareboe Zigbee 3.0 USB Dongle (model "9888010100045") as well as on CoolKit Technologies “SM-011 V1.0” module used in the ITead Sonoff ZBBridge Zigbee Bridge?
Here is by the way link to FCC filing/report for the new “ZBDongle-E” (a.k.a. "ZBD-E" ) adapter which contains copy of the user manual + a lot more detailed + many more internal and external pictures:

https://fccid.io/2APN5ZBD-E/External-Photos/External-Photos-6012451
It at least looks to use the same EFR32MG21A020F768IM32 (EFR32 Mighty Gecko Series 2) SoC used on the first ITead Zigbee 3.0 USB Dongle, as well as on CoolKit Technologies "SM-011 V1.0" module used in th ITead Sonoff ZBBridge Zigbee Bridge and in Tuya ZS3L and Tuya ZSLC5 SoC modules. It includes a 80 MHz ARM Cortex-M33 core, 768 Flash Storage, 64 RAM, in a QFN32 package, which radio has + 20 dBm maximum power output and receive sensitivity of -104 (250 kbps O-QPSK DSSS) dBm.

By the way, news is that a similar Silabs EFR32MG21 SoC will also be used in the official "Home Assistant SkyConnect USB Stick", see:
