SparkFun RTK EVK is a fully-enclosed GNSS platform designed for fixed or mobile high-precision positioning and navigation applications with centimeter accuracy thanks to RTK (real-time kinematic) technology implemented with modules from u-blox. About two months ago, Sparkfun introduced the RTK Torch waterproof GNSS surveyor with Unicore UM980 GNSS module with RTK support, ESP32 for WiFi/Bluetooth, and an STM32WLE5C LoRa SoC. The SparkFun RTK EVK (evaluation kit) may drop LoRa connectivity, but it’s a more versatile platform with WiFi, Bluetooth, Ethernet, and LTE Cat 1 cellular connectivity, besides support for L1 + L2 RTK GNSS with L-Band correction. Sparkfun RTK EVK specifications: GNSS Receiver – u-blox ZED-F9P Concurrent reception of GPS, GLONASS, Galileo, and BeiDou Receives both L1C/A and L2C bands 184-channel u-blox F9 engine Time to First Fix: 25s (cold), 2s (hot) Max Navigation Rate: 20Hz / 25Hz depending on mode Horizontal Position Accuracy: 2.5m without RTK; 0.010m with RTK […]
Beginner friendly Arduino Plug and Make Kit features Arduino UNO R4 WiFi and Modulino I2C modules
Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and various cables, spacers, screws, and nuts. When thinking about Arduino projects, breadboards or even soldering may come to mind, but the new Arduino Plug and Make Kit does not require any of those. No breadboard, jumper wires, or soldering needed. Users can simply connect the modules to the Arduino board through Qwiic cables, neatly attach everything together on the provided base, and follow one of the seven projects complete with step-by-step instructions provided with the kit. The Arduino Plug and Make Kit content Arduino UNO R4 WiFi board 7x Modulino I2C nodes Modulino Knob* – Encoder for value adjustments Modulino Pixels* – 8x LC8822-2020 RGB LEDs Modulino Distance – STMicro VL53L4 Time-of-Flight (ToF) proximity sensor to […]
LILYGO T3S3 E-Paper combines ESP32-S3 WiFi & BLE SoC with LoRa module, 2.13-inch e-Paper display
LILYGO T3S3 E-Paper is an ESP32-S3 WiFi and Bluetooth LE development board with a 2.13-inch e-Paper display and an SX1262 LoRa module that should make it suitable for off-grid messsaging even under sunlight.

ESP32-S3 LCD Driver Board supports both circular and square displays
Waveshare ESP32-S3 LCD Driver Board is a compact development board designed to simplify the GUI development process. The company mentions that the board supports 2.1-inch, 2.8-inch, and 4-inch displays and with an additional SPI and I2C header it can support a wide range of LCD panels. Additionally, the board features an onboard lithium battery charger and 15 usable GPIO pins for added flexibility. These features make this device suitable for applications like smart home devices, industrial control panels, and interactive kiosks. It seems like the board supports the 4-inch LF40 square touchscreen display that we wrote about just yesterday. other than that it also supports 2.1-inch and 2.8-inch circular displays. Seeking off circular displays, we have previously written about some ESP32-powered development boards with circular displays like the Waveshare 1.69-inch IPS touch LCD, the Waveshare RP2040-LCD-0.99-B, the Waveshare ESP32-S3-LCD-1.28 and many other types of displays. Feel free to check those […]
SunFounder PiPower 3 kit is a UPS solution for the Raspberry Pi 5 SBC
