RPI Pico 2040 + WaveShare SX1262

Raspberry Pi Foundation

Semtech SX1262 RP2040 (Dual-Core Arm Cortex-M0+, bis 133 MHz) 22 dBm

This MeshCore-enabled combination consists of a Raspberry Pi Pico (RP2040 microcontroller with a dual-core Arm Cortex-M0+, 264 KB of SRAM, and 2 MB of flash) and the Waveshare Pico LoRa SX1262 expansion module. The LoRa module is based on the Semtech SX1262, featuring a programmable transmit power of up to 22 dBm, a high receive sensitivity of up to -148 dBm, and support for LoRa, FSK, and GFSK modulation, as well as the LoRaWAN protocol. It plugs in via a standard Pico header, features a PH1.25 battery connector with a charge controller, as well as two status LEDs, and is available in different frequency bands (e.g., 433/868/915 MHz) depending on the region. The Pico itself does not have Wi-Fi, Bluetooth, or GPS. It is a DIY combination of two separate components that must be assembled by the user.

Repeater v1.15.0-evo_0.1.21 14.01.2026 Release

⚠️ Check that radio.rxgain(on) and flood.advert.base (0.308) are set correctly after flashing! ⚠️

This build is based on official MeshCore 1.15.0 dev branch (as of 25-May-2026 and additionally includes the following unmerged upstream PRs/changes:

Additional changes:
  • Flood adverts are disabled (flood.advert.interval set to 0) by default
  • :new: modified PR1810 to not block flood adverts but only PAYLOADTYPEGRPTXT and PAYLOADTYPEGRPDATA so that some limited flood advert distribution can be managed via PR2553 to support e.g. observer maps.
Changelog:
  • Based on dev v1.15.0 as of 25-May-2026
