Similar to many others, here is a small IR receiver/transmitter courtesy of atc1441 (though the one he posted about looks different).
I bought this one in late 2024, seems to be still available for $7 on Ali, 1005006823624599
The whole device is just 38 mm diameter, 15 mm thick.
It has a BK7231N on the common CBU board. Four IR leds on top, and a receiver. Blue status LED and a button on the bottom.
Trivial to flash with a USB-serial device, the pins are labelled underneath the board. I usually solder some 30 gauge wires to them.
