🚀 Hands-on with the KT6368A Bluetooth Chip (SOP8, only $1.06 USD!)
Just tested the ultra-low-cost KT6368A, a dual-mode Bluetooth 5.1 chip in a tiny SOP8 package.
Despite its price, it's shockingly easy to use:
🔹 UART-based, supports AT commands
🔹 BLE or SPP (pick one at a time)
🔹 Minimal circuit – just power, crystal, and antenna
🔹 No need for complicated peripherals
