Wio Tracker 1110 Dev Kit for Meshtastic

Seeed Studio Wio Tracker 1110 Dev Kit supports Meshtastic for off-grid communication

The Seeed Studio Wio Tracker 1110 is a dev kit designed to work with the Meshtastic network. The board is built around a Nordic nRF52840 multiprotocol Bluetooth 5.4 SoC and uses the Semtech LR1110 LoRa transceiver for communication. Seeed Studio is selling the Wio Tracker 1110 development board in a bundle with an OLED display and a GNSS receiver, providing everything needed to start experimentation for peer-to-peer LoRa mesh networking. Meshtastic is a free, open-source, decentralized mesh network that uses LoRa radios to establish a low-power, long-range, off-grid communication system in areas without reliable infrastructure. Driven entirely by the community, Meshtastic enables decentralized, encrypted communication without the need for a dedicated router or phone. Previously we have written various versions of the Wio Tracker including the Wio GPS and Wio LTE GPS Tracker. Since Meshtastic projects are becoming popular among developers and enthusiasts, we will likely see many more dev […]

Radxa ROCK 5B+

Upgraded Radxa ROCK 5B+ SBC gets LPDDR5 memory, eMMC flash, WiFi 6, two M.2 M-Key sockets, 4G LTE/5G support, and more

The Radxa ROCK 5B+ (“ROCK 5B Plus”) is an upgrade to the Rockchip RK3588-powered ROCK 5B Pico-ITX SBC with the same form factor but various changes including a switch from LPDDR4x to LPDDR5, optional built-in eMMC flash, and an onboard WiFi 6 and Bluetooth 5.2 module instead of one connected through an M.2 Key-E connector. Other changes include replacing the M.2 Key-M PCIe Gen 3 x4 socket with two M.2 Key-M PCIe Gen3 x2 sockets, adding a SIM card slot and M.2 Key-B socket for 4G LTE or 5G cellular connectivity, adding an extra USB-C port for power only (was multiplexed with USB-C Display Port connected in ROCK 5B), and the HDMI input relies on a full-size HDMI port instead of a micro HDMI port. Other small changes can be found in the specifications below with differences highlighted in bold and strikethrough. Radxa ROCK 5B+ specifications: SoC – Rockchip RK3588 […]

Flipper Zero Add On CANBus

Flipper Zero hacking tool gets CAN bus add-on board for vehicle diagnostics and security research

Electronic Cats’ Flipper Add-On CANBus is a new add-on board for the Flipper Zero adding CAN bus communication to the popular wireless hacking tool. Built around the MCP2515 CAN controller chip this add-on card communicates with the Flipper Zero through an SPI interface. It allows users to sniff, send, and log CAN bus packets directly from the Flipper Zero, which means now you can analyze and manipulate CAN bus traffic for vehicle diagnostics, security research, and DIY projects. Previously we have seen Flipper Zero add an RP2040-powered video game module, and before that, we noted the developers launched their own app store with open-source apps. Additionally, we have written about Flipper Zero alternatives such as the M1 multitool so feel free to check those to know more about those solutions.

LOLIN S3 Mini Pro multi-color PCB board

LOLIN S3 Mini Pro – A tiny ESP32-S3 board with a 0.85-inch display and a multi-color PCB

LOLIN S3 Mini Pro is a tiny ESP32-S3 WiFi and BLE board with a 0.85-inch display and it’s one of the first boards I’ve seen with a multi-color PCB that some PCB manufacturers have been offered recently. The board features an ESP32-S3FH4R2 microcontroller with 4MB flash and a 2MP PSRAM, a 128×128 TFT display, a 6-axis motion/attitude sensor, and GPIO headers that make it compatible with LOLIN D1 mini shields for expansion. LOLIN S3 Mini Pro specifications: SoC – Espressif Systems  ESP32-S3FH4R2 CPU – Dual-core Tensilica LX7 microcontroller @ up to 240 MHz Wireless – 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 2MB PSRAM Storage – 4MB SPI flash Display – 0.85-inch 128×128 LCD TFT display with GC9107/GC9A01 driver Sensor – 6-axis MEMS IMU/attitude sensor (QMI8658C) Expansion 2x 8-pin headers with up to 12x GPIO, ADC, DAC, I2C, SPI, UART, USB OTG; compatible with LOLIN […]

Pico Video4 display board top

Raspberry Pi RP2040-based Pico Video4 display board features 4 composite video outputs

The Pico Video4 Display is a Raspberry Pi RP2040-powered board that supports up to 4 analog composite video display interfaces with dedicated frame buffer memory accessible via SPI. The four video outputs are sent out through an RCA connector and a VGA DB15-HD connector that uses the red, green, and blue channels to create a composite video signal. The Pico Video4 Display is based on the Raspberry Pi RP2040 microcontroller chip and the VLSI VS23S040 four-megabit static RAM device with a video display controller that can output NTSC, PAL, and VGA video from the memory array. It provides the composite video outputs with a dedicated frame buffer and other hardware. This ensures that the RP2040’s limited processing power and memory are not hogged up in generating the video signal, leaving room for other major tasks. It has 8 inputs that are voltage-compatible to the input voltage, from 5V to 12 […]

Blette Stick Bluetooth LE offgrid communication

The Blette Stick relies on Bluetooth 5.0 LE for off-grid messaging with up to 1.1km range

The Blette Stick is a Bluetooth 5.0 LE USB-C dongle designed to be attached to an Android smartphone in order to provide off-grid messaging and GPS coordinates sharing capabilities with a range of up to 1.1km in case WiFi and cellular networks are down. CNX Software readers may also be familiar with Meshtastic devices relying on WiFi to connect to the smartphone with Bluetooth and to other nodes using LoRaWAN to enable off-grid messaging while trekking or during emergencies. The Blettle Stick does something similar to the Meshtastic project but with Bluetooth LE long-range communication instead of Bluetooth+LoRaWAN. While the range will be shorter and limited to around 1km (line-of-sight), the plug-and-play design will make it easier to use for typical users who are not technically savvy. Blettle Stick specifications: SoC – Nordic Semi nRF52 Bluetooth 5.0 LE microcontroller (exact part number not specified, possibly nRF52840) Wireless – Bluetooth 5.0 […]

Rockchip RK3568, RK3588 and Intel x86 SBCs and SoMs in 2025
Radxa X4 x86 Raspberry Pi 5 SBC

Radxa X4 low-cost, credit card-sized Intel N100 SBC goes for $60 and up

Radxa X4 is a credit card-sized Intel Processor N100 single board computer (SBC) that costs almost the same as a Raspberry Pi 5 with the 4GB RAM model going for about $60 and the 8GB RAM variant around $80. The x86 SBC offers many of the same features as the Raspberry Pi 5 including dual micro HDMI output, four USB 3.2/2.0 ports, Ethernet and WiFi networking, and the 40-pin GPIO header handled through a Raspberry Pi RP2040 microcontroller.  Networking is better with 2.5GbE and WiFi 6, M.2 SSD support is built-in and four to eight times faster compared to PCIe HAT for the Pi 5, and the USB 3.2 ports are capable of 10 Gbps speed. So let’s little not too like, and the main downside is the lack of MIPI CSI and DSI connectors for projects requiring those camera and display interfaces. Radxa X4 specifications: SoC – Intel Processor […]
