Nicholas ★★★★★ Aug 16, 2026

The USB to TTL communication has been rock solid for me, and hooking up the external 8-26V DC power really took the guesswork out of feeding my display. It's a compact board, but it feels sturdy enough and hasn't missed a beat in the two weeks I've had it. Definitely doing its job.

Timothy ★★★★★ Aug 14, 2026

The external 8-26V input is a lifesaver for my bench setup—no more unstable voltage drops mid-flash. It’s compact, the connector pins are sturdy, and it handles my 12V supply without heating up.

Finally, a USB-to-TTL board that doesn't drop connection when my other gear pulls power—the extra DC input makes all the difference for stable flashing sessions. Plugged in a 12V supply and it handled the whole job without a hiccup.
