Overview

SendIR – is one of the most advanced IR emitter modules available for sending remote control modulated Infrared signals using a microcontroller. SendIR allows makers, hobbyists and professionals to send infrared signals from their microcontroller projects using quality IR components and excellent design features. SendIR is a drop in replacement for any IR emitter circuit and provides excellent range and signal quality for both 3V3 and 5V systems. It can be powered directly from the microcontroller supply, batteries or via an independent DC power supply. SendIR outputs high quality IR signals, thus ensuring optimum performance, reliability and range every time.

SendIR Block diagram and Pinout

What is SendIR?

SendIR is made up of 3 components:

• The SendIR board module.
• An associated Microcontroller unit such as an Arduino, Teensy, ESP8266/NodeMCU, MSP430, PIC, AVR, Raspberry Pi, FPGA Spark Core, ARM, Edison, PSOC or similar to generate the modulated infrared signal for transmission. (Not Included.)
• A power supply provided via the microcontroller supply or via an independent DC power source. (Not Included.)

SendIR is an excellent companion device for any 5V or 3V3 project and can operate from 2V5 to 5V supplies. It can be configured with single or dual emitters for more demanding projects. Single emitter mode is recommended for 3V3 supply or below, unless dual aspect coverage is the primary requirement.

What’s Included

Each SendIR module is configured with single or dual emitters plus a set of header pins and power selection jumpers (pre-soldered by default). You can opt to have the emitters and header pins soldered or not. Test points and spare positions are not populated.

IR range can be increased further by installing a programming resistor on the PCB. This is a feature of all of our constant current IR emitter designs in the MakeIR Kit series.

A quick-start guide is provided after purchase which covers: input headers, power selector jumper settings, 5v/3V3 operating modes, programmable resistor for custom power levels and Test Points for better understanding of the circuit and trouble shooting. IR range can be increased further by installing a programming resistor on the PCB. This is a feature of all of our constant current IR emitter designs in the MakeIR kit series.
