The item is a terminal expansion adapter, working very well for prototyping Arduino Nano projects. There are pins expansion hole for the NANO board, which can directly lead the pins; With DC power supply interface, you can directly add external power or battery to supply power With NRF2401+ expansion interface, you can insert NRF2401+ to achieve wireless communication Added a filter capacitor to enhance the stability of wireless communication.

- The new version adds filter capacitors, the signal is stronger, and the communication is more stable.
- PCB uses the immersion gold process, exquisite workmanship, immersion gold process stitch expansion hole.
- The new version has an extension interface with NRF2401+.
- Interface optimization, can be directly docked.
- Insert NRF2401+ to quickly achieve wireless communication.
- Power interface, sinking gold process, filter capacitor.
