SB Components Gives the Raspberry Pi Pico RFID Powers with Its Latest Expansion Board Design
Launching soon, the add-on board provides an RFID reader, buzzer, and compact OLED display, as well as full GPIO access.
SB Components is planning to launch an add-on for the Raspberry Pi Pico microcontroller, which offers radio-frequency identification (RFID) support, complete with a 125KHz radio and an on-board display.
"[Our] Raspberry Pi Pico RFID Expansion is the latest technology in the range of SB Components products boasting an advanced RFID reader at the frequency of 125KHz," the company explains of its latest design, "with a compact design that has a programmable 0.91" OLED Display and an updated UART/I2C interface that is compatible with Raspberry Pi Pico."
"It helps the user to read the information of the ID stored on the RFID key fob and tags. Every RFID tag/key fob comes with a unique identity that cannot get copied. There are control jumpers that allow the user to control the OLED, RFID reader, and buzzer pins, other than the default pins."
Designed for use with any 125KHz RFID tag — and coming supplied with one each of a key-fob and credit-card format tag — the reader comes with female headers for a Raspberry Pi Pico microcontroller, male headers for each of its pins, the on-board OLED display, RFID reader, buzzer, and the jumpers for switching peripherals between different general-purpose input/output (GPIO) pins.
The add-on is due to launch imminently, priced at $41 — not including the Raspberry Pi Pico required to drive it. Sample code has been published on SB Components' GitHub repository, with more information available on the company's store page.
