Making a project wireless is cheap and easy thanks to the nRF24L01+ 2.4GHz radio transceiver. This development board made by Ceech caters to a wide range of project requirements whilst still making it easy to get up and running.
Many projects involving transceiver radios need to be battery powered; weather stations and sensor nodes to name two examples. Adding a battery to this board is made easy thanks to the MAX8903 3.7V lithium battery charger included, just solder on a header for a LiPo battery and you are good to go.
The board has a wide input voltage range thanks to the TPS63001 3.3V DC-DC buck-boost converter on-board. Any input voltage from 1.8V to 5.5V will work, making it easier to deal with a variety of power sources like solar panels for example. This buck-boost converter operates with an astonishing 96% efficiency and only draws typically around 30uA.
If your project calls for switching high current loads this board has a 30V 3A N-channel MOSFET to do the heavy lifting. This will let you add wireless control for motors, lights, solenoids, etc. There is a BME280 environmental sensor included on the board which can measure temperature, humidity and barometric pressure.
In summary, this board has high power switching, an environmental sensor, wide input voltage, and a LiPo battery charger. Basically it’s the Swiss Army knife of nRF development boards. Oh and it’s fully Arduino compatible too, with an ATMEGA32U4 microcontroller on the board and the all-too familiar Arduino shield footprint.
