Adafruit RS232 Pal – Two Channel UART to RS-232 Level Shifters – MAX3232E: If you’re looking to interface with telco, retro or industrial equipment you’ll probably run into RS-232 interfaces. The Adafruit RS232 Pal – Two Channel UART to RS-232 Level Shifters is your friend in such cases, giving you two duplex channels of level shifting and taking care of the high/negative voltage generation all in a low cost breakout board. We use the trusty MAX3232E, a classic chip that is part of the MAX232 lineage so you know it will work great for all your RS-232 needs, up to 250Kbps.

Adafruit Infrared IR Remote Transceiver – STEMMA JST PH 2mm – 940nm Emitter + 38KHz Receiver: We’ve got a high-powered infrared emitter board, and a super-sensitive infrared remote receiver board – but why buy two boards when you can pick up one that does both? This board is the Adafruit Infrared Tranceiver breakout, which can transmit and receiver 940nm remote control data in one handy solder-free package.

Please Note: to make this board easy to use, we have both solder-able breakout pads and also a JST PH 4-pin cable. We often use JST PH cables for I2C but this board does not use I2C – the white wire is data from a microcontroller to be emitted over the IR LED, the green wire is demodulated IR remote signal data to a microcontroller. The black wire is ground, red wire is 3V~5V power and logic level.

Adafruit USB Type C Vertical Breakout – Downstream Connection: Throw out all those Mini and Micro B USB cables you have in a plastic bin; the next generation of USB connectors is here with USB C! You will start to see these connectors pop up on all sorts of devices as the industry moves from micro B or lightening to the new standard. Well, at least until the next standard comes out.

This is the vertical version. We also carry a classic ‘horizontal’ USB-C breakout here.

Adafruit HDC3021 Precision Temperature & Humidity Sensor – STEMMA QT / Qwiic: We stock a large number of Temperature/Humidity sensors, so you’re probably wondering why another one? Well, this Adafruit HDC3021 Precision Temperature & Humidity Sensor breakout features the highest accuracy & precision one we’ve see so far! It has the TI HDC302x series chip with typical 0.5% accuracy for the RH sensor (with 0.19% long-term drift) and ±0.1°C typical accuracy for the temperature sensor. All at a very nice price.

This sensor has a true I2C interface for easy interfacing with only two wires (plus power and ground!). That makes it preferable to the janky DHT11/DHT22 sensors. The sensor is 5V safe, so you can use 1.8V to 5V power and logic levels without the need for shifters, so you can power and communicate with it using any microcontroller or microcomputer. With 4 selectable I2C addresses, you can have multiple sensors on one bus – unlike many other fixed-address T/RH sensors.
