PuckJs
PuckJs is cleverly packed bluetooth low power IOT package. It does at first includes many generic sensors but few are well packed in plastic case with Silicon covering. Different to few others this one has got IR transmitter. Magnetometer, thermometer, light and battery level sensors are on the board.
Leds are always costly on Low energy device yet this one has got three of those however, they do not light up continuously instead during different device status and is helpful during hardware debugging. There is a pulsating library available to code it for other purposes as IR led.
On software is this one amazing. It has javascript support out of box as well as Visual coder. Library and sample code is great to get started. javascript direct on Web IDE makes developing way way easier.
So far it is great IOT device but for advance uses like Sensor Tag, a generic BLE interface is missing. Using in raspberry pi one needs to separately design interface for this instead of using GATT tools or bluez.
All in all a bit more sensor would be nice yet a great device.
