Arduino USB Based Vitrual Com Port to IR Transmitter

Our USB to Serial IR products are arduino based and allow you to send or receive infrared codes via a USB emulated serial port. This allows for IR transmission and reception without specialized software like LIRC. Commands can be sent via hex code or raw codes. On the receive side we can provide hex codes, raw codes, or a unique hash.

IR Codes are sent with the following command set: IR_CODE_TYPE,IR_CODE_LENGTH,IR_CODE_HEX_DATA

Arduino Based USB IR Transmitter	$19.95
USB A to mini-B 3 Foot Cable	$2.99

The following values are acceptable for IR_CODE_TPYE:

  - NEC

  - RC5
  - RC6
  - PANASONIC_OLD
  - JVC
  - NECX
  - SAMSUNG36;
  - GICABLE
