Harper ★★★★★

The 2.4 GHz frequency works flawlessly with my home router, and I love how compact it is for hiding behind my sensor projects. Setup was straightforward once I got the baud rate right.

Emily W. ★★★★★

Had to flash the firmware a couple of times to get it working with my setup, but once I did, the range on this little module surprised me—connects reliably from two rooms away.

Emma H. ★★★★★

These little boards punch way above their weight for the price. I was up and running with the 2.4 GHz Wi-Fi in under an hour, and the compact size makes it perfect for my sensor project.
