LoRa Expansion for Raspberry Pi Pico (Inc. Antenna) [Discontinued]

The Pico LoRa Expansion is a low-power consumption data transmission board for the Raspberry Pi Pico. The expansion is available in two versions: 433MHz or 868MHz (select above before adding to cart).

This board is packed with features – it comes with an onboard CH340 USB to UART converter, Voltage Level Translator (74HC125V), SMA antenna connector that covers the 433MHz or 868MHz frequency band, onboard 1.14′ LCD, IPEX antenna connector and LoRa Spread Spectrum Modulation technology with auto multi-level repeating.

The Pico LoRa Expansion has been developed to enable data transmission up to 5 KM through the serial port. With the new generation LoRa spread spectrum modulation technology, a user can easily transmit data with low-power consumption. The board distinguishes itself from the normal LoRa with its longer communication distance, lower power consumption and better safety and anti-inference system.

The USB-UART communication of Pico LoRa enables direct communication with a desktop/laptop without using a Raspberry Pi Pico. A comprehensive product Wiki includes everything you need to get started. Antenna included.

Note: Raspberry Pi Pico not included. You’ll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
