ZeeKey

The ZeeKey is a versatile sensor platform integrating RF module, power supply and various sensors. This version of the ZeeKey features a sensor to measure light, temperature and orientation of the device, which sports dimensions of the 40x19x7.1 mm (excluding battery pack).

We are using Zigbee modules named ZigBit made by Meshnetics (http://www.meshnetics.com). They can be programmed either via JTAG or using a pre-flashed serial bootloader. The latter waits for a combination of bytes for the first 500ms after booting before it hands over control to the program itself. If the right
startup combination is found, an srec file can be sent to the module.
