Warning:
1.This module requires a 3.3 volt supply for VCC, and 3.3V logic

2.It is not 5V tolerant, connecting RX or TX with 5V supply will destroy this module

3.You must use a logic level converter, or a 3.3V for Arduino

4.The 3.3V supply on the FOR Arduino Uno has inadequate current capability to power this module

5.You must provide a separate, higher 3.3V supply(about 300mA or better)

Customer Reviews (4.6 / 5 · 5 reviews)

Elizabeth ★★★★★

Built a small relay controller with this and it connected to my router in under a minute. The +25dBm output means it reaches across my whole apartment, even through two walls. Just remember the 3.3V logic limit before you fry it like I almost did.

Jason S. ★★★★★

Used it to build a wifi temperature sensor for my greenhouse, and the 802.11b/g/n connection stays stable even with the metal frame nearby. Just make sure you give it exactly 3.3V on VCC—I fried one by accident using 5V logic.

Henry ★★★★★

The 2.4GHz range is solid for my IoT sensors, and I appreciate that the power output hits +25dBm for better signal penetration. Just remember to keep it at 3.3V logic—I blew one by accident before reading the warning.
