Its transmitter and receiver are independent, there is no automatic echo suppression. The receiver is based on [TSDP34156](http://www.vishay.com/docs/82667/tsdp341.pdf) IR receiver. The transmitter is built using [TSAL6400](https://www.vishay.com/docs/81011/tsal6400.pdf) 940 nm IR LEDs and a carrier generator based on [74HC132](https://assets.nexperia.com/documents/data-sheet/74HC_HCT132.pdf) quad-NAND CMOS gate.\n\nThe nominal transmission rate is 9600 baud. The carrier generator should be tuned to 57.6 kHz (with 6 cycles per bit it gives $57600 / 6 = 9600$ baud).\n\nThe adapter can be powered from 3.3 V or 5 V and will operate with the corresponding logic levels.\n\nThe board size is just 21x36 mm and provides 8 unconnected PTH (plated through holes) for mounting purposes. It should fit the [Pico (RP2040)](https://datasheets.raspberrypi.com/pico/pico-datasheet.pdf) board well.\n\n| · | · |\n| - | - |\n| ![Assembly top view](images/assembly-top.png) | ![Assembly overview](images/assembly-overview.png) |\n| ![PCB top view](images/pcb-top.png) | ![PCB bottom view](images/pcb-bottom.png) |\n\n![Schematic](images/schematic.svg)\n\n## Performance\n\nWith minor adjustments after the first tests, the modules work as expected transmitting and receiving 1 kHz test signal. Using the modules with UART hasn't been tested yet.\n\nSome more photos and/or info may be found at [hackaday.io/project/195022-ir-uart](https://hackaday.io/project/195022-ir-uart).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwerediver%2Fir-uart","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fwerediver%2Fir-uart","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwerediver%2Fir-uart/lists"}
