zzh is the original "USB stick" form-factor development board for TI's new generation CC2652R chips.
- TI CC2652R1 2.4 GHz multi-protocol wireless microcontroller targeting Thread, Zigbee, Bluetooth 5 Low Energy, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN) and proprietary systems
- Communicates with the host computer via the common CH340 USB-UART bridge, no manual driver installation needed in most cases (Windows and Linux)
- Self-programming via the TI CC-series serial bootloader. As long as it is not explicitly disabled in code, no external programmer needed! Pushbutton on the default pin to trigger this mode
- cJTAG debug header, in case you disable BSL by accident or want a proper debug interface
- SMA antenna port for an external antenna of your choice
- General purpose LED
Think of it as an upgrade to the ubiquitous CC2531 USB Sticks commonly used for Zigbee tinkering. CC2652 has a much beefier processor, more memory and a sane free compiler that should enable easier development compared to the old 8051 based CC2530/1 devices.
A portion of each sale will be donated to @Koenkk to support his work on Zigbee2mqtt and the public firmware images used by zzh and many other projects.
What is included?
Each order contains a fully assembled and tested PCBA along with a plastic enclosure and an antenna. An optional debug adapter kit of parts (requires assembly) can also be purchased. Please refer to the listing photos.
Please keep in mind that zzh is a general purpose development board. It is shipped with a simple test program that just blinks the LED on and off (with no radio functionality) to verify that the MCU is running. You will need to program it before it does anything meaningful. Given the application dependent nature of this board, limited after-sales support can be provided (For example: we can help you program this board but can't fix your Zigbee network range issues or offer specific software support).
