John X. ★★★★★ Oct 22, 2026

Finally got my two-way Bluetooth link working—the 3.6V to 6V input range made it easy to power with a standard 5V supply. Very stable connection after pairing to the slave module.

Daniel ★★★★★ Oct 21, 2026

Worked perfectly with the matching slave module I already had—pairing was instant once I set the baud rate correctly. The 3.6 to 6V range made it easy to power from my project board without extra regulators.

Robert J. ★★★★★ Oct 20, 2026

Connected this to my Arduino and it paired instantly with the slave module. Data transfer is clean and stable, even at longer distances than I expected.
