SB Components’ 2×2 Quad Display Board is an MCU development board fitted with either a Raspberry Pi Pico W board or an ESP32-S3-WROOM-1 module used to drive four small color displays in square or round shapes. The board specifically features either four 1.54-inch square TFT displays or four 1.28-inch round displays, a microSD card, an RTC with coin-cell battery holder, and a USB-C port for power and programming, plus a few buttons. It may feel like it’s coming out of the but-why-because-we-can department, but the company expects it to be used for signage, interactive displays, art projects, portable devices, data loggers, education, and more. 2×2 Quad Display Board specifications: Main control (one or the other) Raspberry Pi Pico W MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash Wireless – WiFi 4 and Bluetooth LE 5.2 USB – 1x Micro [...]

The Waveshare ESP32-H2-DEV-KIT-N4-M is a development board based on the ESP32-H2, available for only $6.65 on Aliexpress, but you’ll also find it on Amazon and Waveshare’s official store. This is a significant price drop compared to last year’s official Espressif ESP32-H2-DevKitM-1 board, which was priced at $10 without including shipping costs and with a similar design. In 2021, Espressif Systems introduced the ESP32-H2 to the world. However, it wasn’t until 2023 that they released their first development board. Since then, there haven’t been many products built around this new module. Some exceptions include the Olimex ESP32-H2-DevKit-LiPo, LILYGO T-Panel, and the ESP Thread Border Router/Zigbee Gateway board, all of which feature the ESP32-H2 chip. Waveshare ESP32-H2-DEV-KIT-N4-M specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh, and 802.15.4 (Zigbee/Thread/Matter) radios.

Arduino Nano 33 BLE Rev2 is an update to the Arduino Nano 33 BLE board launched in 2019 that features two IMU sensors instead of one with the BMI270 6-axis accelerometer and gyroscope and the BMM150 3-axis magnetometer and also comes with a few changes made after feedback from users. The new board is still powered by an nRF52840 Bluetooth LE module (u-Blox NINA B306) and remains Arduino Nano compatibility with two rows of 15-pin headers, but replaces the 9-axis IMU with the BMI270 and BMM150 chips, adds new pads and test points for USB, SWDIO, and SWCLK, a new VUSB soldering jumper, and brings changes to the power circuitry. Arduino Nano 33 BLE Rev2 specifications: Wireless Module – U-blox NINA B306 module SoC – Nordic Semi nRF52840 MCU Core – Arm Cortex-M4F microcontroller @ 64MHz Memory and storage – 1MB Flash, 256KB RAM Bluetooth 5.0 LE Up to 2 [...]

Arduino board clones have been around for many years, but I don’t think I have ever seen clones of the new Renesas-based Arduino boards so far. Waveshare changes that with the R7FA4 PLUS A that clones with Arduino UNO R4 Minima, and the R7FA4 PLUS B board duplicating the Arduino UNO R4 WiFi. The Waveshare boards are not 100% clones with some small differences in the PCB layout, support for 5V and 3.3V shields, an additional 6-pin “power output header” with 5V, 3.3V, and GND signals, and a USB communication jumper to select between the Espressif ESP32-S3 and Renesas RA4M1 microcontrollers. Waveshare R7FA4 PLUS A and B specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash Wireless (B model only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core Xtensa LX7 microcontroller with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity, PCB antenna [...]

We’ve already covered a range of ESP32-C6 boards, but none supporting Ethernet and PoE so far, and the ESP32-C6-Bug board brings that to the table thanks to the Esp32-Bug-Eth shield with a W5500 Ethernet chip, an RJ45 jack and a PoE power module. Like other ESP32-C6 devices, the little board supports Wi-Fi 6, Bluetooth LE 5, as well as Thread and Zigbee through its 802.15.4 radio, but it also integrates some other interesting features such as castellated holes for easy soldering on a carrier board and support for LiPo batteries with built-in battery charging and protection circuits. ESP32-C6-Bug board specifications: SoC – ESP32-C6FH4 MCU cores 32-bit RISC-V core @ 160 MHz 32-bit RISC-V core @ 20 MHz low-power coprocessor can run tasks even when the main system is in deep sleep state Memory – 512 KB SRAM Storage – 4 MB Flash Wireless – WiFi 6, Bluetooth LE 5, and [...]

Waveshare has recently launched two new ESP32-S3 4G dev boards – the ESP32-S3-SIM7670G-4G and the ESP32-S3-A7670E-4G. These boards support 4G LTE Cat-1, Wi-Fi, Bluetooth, and GNSS, and come with an OV2640 camera, and a battery holder for a 18650 battery. The main difference between the two is that the A7670E module also supports 2G GSM/GPRS/EDGE at 900/1800MHz while the SIM7670G module does not. The board has two rows of I/Os including GPIO, I2C, SPI, ADC, and USB 2.0. It also has a USB-C port for power and programming, a slot for a MicroSD card, and an option to connect an external speaker. There’s a USB switching IC and DIP switch for easily connecting the module to a PC for internet or debugging. Waveshare ESP32-S3 4G Dev Boards Specification: Communication module A7670E 4G – A7670E Cat-1 4G module supporting 4G Cat-1 + 2G networking, GNSS positioning, telephone calls, and SMS.

Flipper Zero hardware & wireless hacking tool can now be used as a proper game console thanks to a Raspberry Pi RP2040-powered video game module that mirrors the display of the device on a larger monitor or TV via DVI/HDMI video output, and also adds a 6-axis motion tracking sensor. The Flipper Zero has been in the news in recent days, notably with Canada’s government banning the device due to car theft (although it only seems feasible on older cars), and today the company has announced the launch of a video game module developed in collaboration with Raspberry Pi Ltd. Video game module specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller clocked up to 133 MHz with 264 kB SRAM Video Output – DVI-D at 640х480 with 60 Hz refresh rate.

The NRFICE FPGA is a Bluetooth FPGA board designed for edge computing and IoT applications. It is built upon a combination of the dual-core nRF5340 Bluetooth SoC and the Lattice ICE40UP5K FPGA. The ICE40 UltraPlus is a low-power, high-performance FPGA for edge computing and artificial intelligence projects and the nRF5340 is a Bluetooth 5.3 SoC that supports Bluetooth Low Energy (BLE), Bluetooth Mesh, Thread, NFC, and Zigbee. Through the Nordic nRF5340, NRFICE can load a project directly into the iCE40 FPGA, bypassing the usual extensive toolchain setup. This enables a new class of FPGA development, where bitstreams can be hosted in the cloud, selected by a user on their phone, and loaded wirelessly to the board. It features a built-in J-Link OB for easy debugging and programming without the need for emulator dongles and is similar to the previously covered Segger emPower evaluation board in this regard. This board supports [...]
