Raspberry Pi Pico SDK 2.1.1 release adds 200MHz clock option for RP2040, various Waveshare boards, new code samples

Raspberry Pi RP2040 200 MHz

The Raspberry Pi Pico SDK 2.1.1  has just been released with official 200 MHz clock support for the Raspberry Pi RP2040 MCU, several new boards mostly from Waveshare, but also one from Sparkfun, as well as new code samples, and other small changes. Raspberry Pi RP2040 gets official 200 MHz clock support When the Raspberry Pi RP2040 was first released along with Raspberry Pi Pico in 2021, we were told the default frequency was 48 MHz, but the microcontroller could also run up to 133 MHz. Eventually, I think the Cortex-M0+ cores were clocked at 125 MHz by default, although some projects (e.g. PicoDVI) would boost the frequency up to 252 MHz. Frequencies higher than 133 Mhz were not officially supported so far, but the Pico SDK 2.1.1 changes that since the Raspberry Pi RP2040 has now been certified to run at a system clock of 200MHz when using a […]

SparkFun introduces Quadband GNSS RTK Breakout board with Quectel LG290P module for high-precision navigation

SparkFun Quadband GNSS RTK Breakout

SparkFun has released the Quadband GNSS RTK Breakout featuring the Quectel LG290P module designed for high-precision real-time kinematic (RTK) applications. It supports GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations, with the ability to simultaneously receive signals from L1, L2, L5, and L6/E6 frequency bands. The module includes support for SBAS augmentation systems (e.g., WAAS, EGNOS, GAGAN) and PPP services (e.g., BDS PPP-B2b, QZSS CLAS), delivering reliable positioning with fast convergence times for precision navigation tasks. The breakout board offers a compact design (43.2 x 43.2mm) and multiple expansion options including 24 PTH pins, dual 4-pin JST Qwiic connectors, three UART interfaces, a USB-C connector, and additional PTH pins for BlueSMiRF/Serial-to-UART. With its RTK support and advanced GNSS capabilities, the board is ideal for applications requiring high-accuracy positioning and robust navigation performance. Previously, we covered several GNSS boards including the SparkFun GNSS L1/L5, u-blox EVK-LEXI-R10, and Conexio Stratus Pro and […]

SparkFun’s $125 “Indoor Air Quality Combo Sensor” combines the SCD41 and SEN55 environmental sensors

SparkFun Indoor Air Quality Sensor

SparkFun has released a new air quality multi-sensor board, the Indoor Air Quality Combo Sensor, which integrates the SCD41 and SEN55 sensors from Sensirion for measuring carbon dioxide, volatile organic compounds (VOCs), particulate matter, relative humidity, and temperature. The air quality multi-sensor board simplifies power management for the two sensors via onboard DC voltage conversion and allows a single Qwiic connection for power and communication. It features two Qwiic connectors and a 0.1”-space through-hole header for I2C and power. The board is not a complete solution for indoor air quality monitoring. It has to be connected to a Qwiic-enabled microcontroller such as SparkFun Thing Plus Matter, DataLogger IoT, and the ESP32 Qwiic Pro Mini. Users can install the required Arduino libraries — the Arduino Core library, Sensirion I2C SEN5x, and SparkFun SCD4x — either via the Arduino library manager or directly from SparkFun. The device is open-source, with hardware files, […]

Raspberry Pi Pico Arduino core 4.0 adds support for RP2350 boards

Raspberry Pi RP2350 Arduino

Earle F. Philhower, III has just released the Raspberry Pi Pico Arduino core 4.0 with support for a range of Raspberry Pi RP2350 boards beside the official Raspberry Pi Pico 2. Shortly after the RP2040-based Raspberry Pi Pico board was released, we got two Arduino SDKs, the first being the community-supported Raspberry Pi Pico Arduino core maintained by Earle, and the second being the official Arduino Core Mbed 2.0 for boards as such as Arduino Nano Connect RP2040. We are again likely to have two Arduino SDKs for the RP2350 starting with the Raspberry Pi Pico Arduino core. Key changes in Raspberry Pi Pico Arduino core 4.0: Adds Raspberry Pi RP2350 support (Arm only; RISC-V cores are not supported at this stage) Migrates to Pico SDK 2.0 since it is required for RP2350 support and includes a new OpenOCD and Picotool. Tested features: SPI, I2C, LittleFS, EEPROM, PWMAudio, LWIP-based networking, […]
