Greetings,
I’ve created a wireless controller for my hobby that is working quite well. I’ve created a transmitter that makes use of an Arduino Nano along with a short range nRF24L01. This transmitter fits into a nice enclosure that includes a battery compartment that holds a 9V battery. My question centers around the possibility of replacing this 9V battery with a rechargeable LiPo battery (or anything else that might work better). Is there anyone that can lead me to how I might achieve the 5 volts needed? I figure that I will need one of the components that would manage the battery while also recharge the battery, but I’m just stuck on where to start. Any and all suggestions would be greatly appreciated.

Hi Dale.
Does your system need to be powered all the time or just when you’re using it? You might look into using our [LiPo Charger/Booster board, that will give you 5 volts from a 3.7 volt LiPo and can charge the LiPo as well. You’d probably want to add a switch to turn it off when not in use though so that it doesn’t drain your battery.](SparkFun LiPo Charger/Booster - 5V/1A - PRT-14411 - SparkFun Electronics)
Hi Chris,
Thank you for your quick response. The remote does have to be on during operation. When there is no activity (adjustments, etc.) and still in operation, the remote at the least sends out a heartbeat to let the receiver know that we are still in operation. However, this heartbeat is a large reduction in communication. I’m very interested in the LiPo Charger/Booster and am planning to try this out as my power source once it is available again.
Many thanks!
Dale
