New Raspberry Pi + nRF24L01+ shields
Connect PA+LNA modules to your Raspberry Pi
I recently had some circuit boards made, as I have had enough experience working with nrf24l01 radio modules that I've encountered numerous issues regarding power supplies and the need for additional capacitors soldered to the radios.
These boards connect to the 5v pins of the Raspberry Pi, which can supply plenty of current for the radios, and converts it down to 3.3v. I've designed two boards, one that fits inside the case, and the other that fits outside the case, so they should work with most cases, though some cases may need modifications. The designs both use a 26-pin header, so they are compatible with earlier versions of Raspberry Pi as well.
Raspberry Pi - nRF24L01+ adapters
These adapters will support even the PA+LNA versions of the radios, so you can extend the range of your wireless networks considerably over the standard modules. They include extra capacitance, with capacitors placed right beside the VCC and GND pins of the radios, so there is no need to solder on additional capacitors.
