GL.iNet Flint2 AX6000 router supports up to 900 Mbps WireGuard VPN with MediaTek MT7986 SoC

GL.iNet Flint2 (also known as GL-MT6000) is a new AX6000 router based on MediaTek MT7986 (Filogic 830) Arm SoC and supporting VPN speeds of up to 900 Mbps using WireGuard and 190 Mbps with OpenVPN. This caught my attention, as I previously covered other GL.iNet routers such as the Spitz AX (GL-X3000NR) and the Beryl AX (GL-MT3000) based on the previously generation Filogic 820 (MT7981B) CPU with claims of (only) 300 Mbps transfer rates with Wireguard, so the new model is supposed to triple the VPN performance. GL.iNet Flint2 (GL-MT6000) specifications: SoC – MediaTek MT7986 (Filogic 830) quad-core Arm Cortex A53 processor @ 2.0 GHz with hardware acceleration engines for Wi-Fi offloading and networking System Memory – 1GB DDR4 Storage – 8GB eMMC flash Networking 2x 2.5 Gbps Ethernet ports 4x Gigabit Ethernet LAN ports 802.11b/g/n/ac/ax WiFi 6 with 4x external Wi-Fi antennas Up to 1,148 Mbps @ 2.4 GHz […]

Arduino GIGA R1 WiFi board gets touchscreen display shield

The Arduino GIGA Display Shield is a 3.97-inch RGB touchscreen display designed for the Arduino GIGA R1 WiFi board introduced a few months ago with an STM32H7 dual-core Cortex-M7/M4 microcontroller and a Murata 1DX module for WiFi 4 and Bluetooth 5.1 connectivity. Besides featuring an 800×480 touchscreen display, the new shield offers some other features such as an MP34DT06JTR digital microphone, a Bosch BMI270 six-axis IMU, a 20-pin Arducam camera connector, and an RGB LED. Arduino GIGA Display Shield (ASX00039) specifications: Display – 3.97-inch touchscreen display with 800×480 resolution (model: KD040WVFID026-01-C025A),  16.7 million colors, 5-point touch, connected over I2C Camera I/F – 20-pin ArduCam camera connectors Sensors Bosch SensorTech BMI270 6-axis IMU with 16-bit tri-axial gyroscope and a 16-bit tri-axial accelerometer STMicro MP34DT06JTR MEMS microphone Misc -1x RGB LED (I2C) Supply Voltage – 3.3V Dimensions – 106 x 80 mm The new shield can be mounted to the GIGA R1 […]

Microchip PIC18-Q20 low-pin count MCU comes with up to two I3C interfaces

Microchip PIC18-Q20 is a new family of microcontrollers (MCUs) with a low-pin count (14 and 20-pin packages) that integrates up to two I3C interfaces as well as multi-voltage I/O (MVIO) interfaces. MIPI I3C was first teased in 2014, then officially announced in 2017, and the first MIPI I3C specification was released the following year, as a backward compatible update to I2C with lower power consumption, and higher bitrate allowing it to compete against SPI. We’ve seen it used in a few application processors and microcontrollers, but it’s the first time I3C can be found in a lower-cost, low-pin count microcontroller. Microchip PIC18-Q20 specifications: Core – PIC18 8-bit RISC microcontroller core @ 64 MHz Memory – 1KB to 4KB RAM Storage – 16KB to 64KB with Memory Access Partition (MAP) support, 256B EEPROM  Peripherals Up to 2x I3C device interfaces Adhere to MIPI I3C Basic Specification 1.0 Support Target Reset Action […]

Review of ALLPCB PCB manufacturing services with an ESP8266 board (Sponsored)

ALLPCB, a PCB manufacturer based in China, has offered us to review their PCB manufacturing services. We’ve taken them up on their offer and will report our experience with the ordering process, shipping, and the board itself, in this review. We will be using the E66 Transmitter board based on an ESP8266 module, and designed to read values from an I2C sensor and send them over RS485 using the Modbus RTU protocol for a range of up to 1.2 km. Since the E66 Transmitter can also connect to WiFi thanks to the ESP8266 module, Modbus TCP is also supported. Since we have our PCB design ready, we can go to the ALLPCB website to start the ordering process. We just had to upload the Gerber files, and then select parameters such as the number of boards, the number of layers, thickness, material type, and whether to include a Stencil or […]

Sparkfun launches cheaper no-code “DataLogger IoT” board compatible with Qwiic modules

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and […]

Pico QwiicReset board adds Reset button and Qwiic connector to Raspberry Pi Pico

Pico QwiicReset is a tiny add-on board for the Raspberry Pi Pico that adds a Reset button as well as the Qwicc connector to more easily connect I2C modules to the popular MCU board. The lack of a Reset button on the Raspberry Pi Pico has always been an issue since the reset pin is used to flash the firmware, so people have tried various ways to add a Reset button to the Pi Pico board. The Pico QwiicReset is like an extension of the Pimoroni “Captain Resetti” button with an extra Qwiic connector. The Pico QwiicReset board is shown soldered to a Raspberry Pi Pico board above, but it’s also compatible with the Raspberry Pi Pico W and it works with or without headers soldered to the board. But you may noticed the Debug header is partially covered on Pico W, which means the add-on board cannot be used […]
