CYKPYK-IR

Standalone IR-over-Ethernet transmitter built on RP2040 with hardwired W5500 Ethernet. Open a TCP connection to port 5001, send a Pronto Hex string — the device fires the IR code in under 5 ms. No special drivers on the control system side. Works natively with RTI Control, Crestron, Extron and any custom TCP client.

Two independent IR output channels: built-in LED (940 nm, direct line-of-sight) and 3.5 mm mini-jack for an external IR blaster cable placed anywhere in the room. Select INT, EXT, or BOTH per command. 38 kHz PWM carrier generated by RP2040 hardware PWM — stable, jitter-free.

Tag system: store up to 32 named Pronto Hex codes in onboard flash. Trigger by name instead of resending the full hex string each time — significantly reduces RTI, Crestron and Extron programming overhead. NEC shorthand syntax supported: supply 3-byte addr+cmd and the firmware builds the complete 4-burst NEC Pronto frame automatically.

Ships with access to an 81,000-code IR database covering 8,900+ devices across 800+ manufacturers — projectors, displays, AV receivers, screens, climate units and more. Configured via TCP port 5000 or USB-CDC. DHCP or static IP.
