Raspberry Pi Gets 5G Cellular Connectivity with Snapdragon X55 Powered HAT

The Raspberry Pi board has long been able to connect to cellular networks either via USB dongles or 3G or 4G LTE HATs that often include GPS as a bonus. But you can now connect your Raspberry Pi 4 or other RPI SBC with a 40-pin header to 5G networks thanks to Waveshare SIM8200EA-M2 5G HAT for Raspberry Pi powered by Qualcomm Snapdragon X55 multi-mode multi-band modem offering 5G/4G/3G cellular connectivity. As we can see from the photo, the 5G add-on comes as part of a cool-looking kit with bottom and top acrylic plates, spacers, a cooling fan plus five antennas for cellular and GNSS connectivity. But the HAT itself integrates a SimCOM SIM8200EA-M2 M.2 module and offers the following specifications: Compatibility – Works with Raspberry Pi boards with a 40-pin GPIO extension header Cellular Connectivity SIM8200EA-M2 core module based on Qualcomm Snapdragon X55 platform with multi-mode multi-band support 5G/4G/3G […]

Tiny Rock Pi S SBC gets PoE & audio HAT add-on board

Powered by a Rockchip RK3308 quad-core Cortex-A35 processor, Radxa Rock Pi S single board computer was launched with specifications listing PoE support via an add-on board. Just one little problem though: it was not available for sale. The good news is that Radxa has now launched a PoE HAT for the Linux SBC adding support for 802.3af PoE up to 10W input, making it one of the smallest single board computers with PoE support in the world, and adding audio features with a 3.5mm audio jack, and an FPC connector for a microphone array. It can be purchased on Seeed Studio for $13.00. Here are the specifications of the complete solution with Rock Pi S SBC and PoE HAT: SoC – Rockchip RK3308 quad-core Arm Cortex-A35 processor @ up to 1.3 GHz with built-in Voice Activity Detector (VAD) System Memory – 512MB RAM Storage – 1GB SD NAND flash, MicroSD […]

Monarch Go Pi HAT Adds LTE Cat M1 Connectivity to Raspberry Pi Board

After introducing Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi earlier this month, Avnet is back with another Raspberry Pi HAT namely Monarch Go Pi HAT that adds LTE Cat M1 connectivity to Raspberry Pi boards and other compatible SBC’s with a 40-pin GPIO header. The expansion board gets its name from Sequans Monarch Go LTE-M modem itself based on the Sequans Monarch GM01Q LTE IoT module that supposed to support both LTE Cat M1 (eMTC) and NB-IoT. The solution is certified by various operators in North America, Europe, and Asia, and ships with a Verizon ThingsSpace IoT SIM. Monarch Go Pi HAT specifications: LTE IoT Connectivity Sequans Monarch Go LTE modem with  Cat-M1 (& NB-IoT?) connectivity Pre-installed Verizon ThingsSpace IoT SIM USB – Micro USB port for debugging and programming Expansion MikroElektronika shuttle click site with 3.3V I/O:  I2C, SPI, GPIO, UART Voltage I/O translator – 1.8V to […]

MEGA-RTD Raspberry Pi HAT Offers up to 64 Resistance Temperature Detectors (Crowdfunding)

Sequent Microsystems like to make stackable Raspberry Pi HATs. After their stackable 4-relay board allowing for up to 32 relays controlled by a Raspberry Pi board, the company has now launched MEGA-RTD 8-channel RTD Raspberry Pi HAT enabling up to 64 resistance temperature detectors via 8x MEGA RTD board stacked on top of a Raspberry Pi board. If you haven’t heard about this type of temperature sensors, we wrote a post explaining the advantages and drawbacks of resistance temperature detectors last year. Basically, those temperature sensors contain a resistor that changes resistance value as their temperature changes, and support much wider temperature ranges than traditional temperature sensors such as DHT22 while keeping a <0.1°C accuracy. The price of the sensors themselves is similar to traditional sensors, but the total price is more expensive since they require extra hardware to measure the resistance/voltage value. MEGA-RTD key features and specifications: MCU – […]

Is That a Raspberry Pi Zero? Nope. ATMegaZero is an Arduino Compatible Board

ATMegaZero is an Arduino Leonardo compatible board based on Microchip ATmega32U4 8-bit AVR microcontroller that mostly follows Raspberry Pi Zero form factor with the 40-pin GPIO header, MicroSD card slot, and one micro USB port in the same location. The MIPI CSI camera connector makes place for an OLED display connector, and the HDMI port is obviously gone, but you also get an 8-pin  header to easily install an ESP8266 based ESP-01 module to add WiFi connectivity. ATMegaZero specifications: MCU – Microchip ATmega32U4 microcontroller running at 16MHz with 32KB Flash, 2.5KB SRAM, 1KB EEPROM Storage – MicroSD card Display – 32-pin OLED display port compatible with 30-pin SSD1306 and SSD1331 based displays Wireless Connectivity – 8-pin header for optional ESP8266 ESP-01 WiFi module Expansion – 40-pin Raspberry Pi-inspired GPIO header with UART/SPI/I2C Debugging & Programming – Micro USB port, 6-pin programming header Misc – 4x LEDs, button Power Supply – […]

Sparkfun Launches the ZED-F9R GPS Dead Reckoning Raspberry Pi pHAT for Mobile Robots

The SparkFun ZED-F9R GPS pHAT module is targeted at single board computers like the Raspberry Pi, Jetson Nano, and other boards with the 2 x 20mm header form factor supporting the GPS RTK (Real-time kinematic) capable of centimeter-level accuracy. Dead Reckoning in robotics allows one to calculate one’s position by using a previously known location or landmarks. Dead Reckoning is an essential aspect of robot navigation, especially Autonomous vehicles like mobile robots or  UAVs. For dead Reckoning to be realistic and minimize the position uncertainty, it usually requires the fusion of position estimation sources like Lidar, Radar, IMU, Odometry, GNSS, accelerometer, and some others. Sparkfun understands this and has launched the Dead Reckoning add-on module that can be used for applications in mobile robots, UAVs, and others. The Sparkfun ZED-F9R GPS pHAT is an exciting sensor fusion board (having been a fan of Extended Kalmar Filter) that provides accurate and […]
