ITead use same CC2652P chip in ZBMINI-L, S26R2ZB, and Sonoff Zigbee 3.0 USB Dongle Plus now.

Note that Sonoff S26R2ZB which has same chip has reported work terrible as a Zigbee Router which is likley due to a firmware bug, read → https://github.com/Koenkk/zigbee2mqtt/discussions/10909

CC2652P1 / CC2652P1F → https://dev.ti.com/tirex/explore/node?node=AP7vVb5x.JDz3X9XOCv9Zw__coGQ502__LATEST

It should be however…

Note! CC2652/CC1352 uses cJTAG (IEEE 1149.7) interface with no SWD (Serial Wire Debug) access using TDI/TDO so only exposes TMS/TCK instead of SWD/SWDCLK thus needing (c)JTAG debug probe which supports cJTAG programming mode which can send required magic byte array.

The cheapest option for an officially supported debugger is Texas Instruments CC-DEVPACK-DEBUG:

The official TMDSEMU110-U XDS110 JTAG Debug Probe is better option though as offer more options:

Texas Instruments XDS110 JTAG debug probe is a bit expensive but cheap clones of it should work, ex:

Also, note that original Segger J-Link V9 (legacy) debug probes does not support cJTAG, so need at least a Segger J-Link V10:

Similarly, if you messed up the bootloader firmware when flashing a CC2562/CC2352 based Zigbee Coordinator USB adapter like Sonoff Zigbee 3.0 USB Dongle Plus then the only way to unbrick the hardware is to flash with cJTAG via the TMS/TCK port:

Would be great if it could set TX power (transmission amplification) to whatever you want and support some standard external sensors that PTVO custom firmware support like temperature and humidity.
