Clintech Pico – The first Raspberry Pi RP2354B board offers 48 GPIOs in Raspberry Pi Pico form factor

Designed by Clintech Ltd. in Bulgaria, the Clintech Pico Board appears to be the first development board based on the Raspberry Pi RP2354B chip with 2MB on-chip flash. It retains the same form factor as a Raspberry Pi Pico 2 but adds extra GPIOs to make use of the 48 general-purpose GPIOs provided by the RP2354B chip. Like the Raspberry Pi Pico 2, this board features 40 castellated and through holes on the sides, exposing GPIOs 0–22 and 26–28, along with 3 debug pins. Additionally, the board includes 27 extra on-board through holes that break out the remaining GPIOs (23–25 and 29–47) as well as the QSPI interface (SD0–SD3 and SCLK) for external memory. Clintech Pico specifications: SoC – Raspberry Pi RP2354B CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot Dual-core 32-bit RISC-V Hazard3 @ 150 MHz (3-stage in-order pipeline; RV32IMAC with Zba, Zbb, Zbs, Zbkb, Zcb, Zcmp, and […]

Avaota F2 – Allwinner V861 RISC-V SBC targets AI cameras with PTZ and audio support

Avaota F2 is the first SBC based on an Allwinner V861 dual-core 64-bit RISC-V SoC with 128MB on-chip DDR3 memory, support for 4K cameras, a H.265 video codec, and a 1 TOPS AI accelerator. It’s an update to the earlier Avaota F1 camera board based on an Allwinner V821 SoC. The new open-source hardware F2 SBC offers several benefits, including support for both Full HD and 4K camera sensors, motor control for the PTZ (Pan-Tilt-Zoom) feature, and improved audio support through speaker (one) and microphone (two) connectors. However, the F1 also included WiFi, which the Avaota F2 lacks. Avaota F2 specifications: SoC – Allwinner V861M2-XXX CPU Dual-Core RISC-V XuanTie C907 (RV64GCBV/RV32GGCBV) clocked up to 1.4GHz with RVV 1.0 extensions Single-core RISC-V XuanTie E907 (RV32IMAFC) clocked up to 800MHz VPU Video Encoder H.264/H.265 up to 4K @ 25fps (M)JPEG up to 8192×8192 Video Decoder – (M)JPEG up to 1080p60 AI accelerator […]

M5Stamp C6LoRa tiny (18×15×2.3 mm) SMD module pairs ESP32-C6 with SX1262 LoRa chip

The M5Stamp C6LoRa is a compact LoRa SMD module that combines the ESP32-C6 Wi-Fi 6, Bluetooth LE, and 802.15.4 microcontroller with the SX1262 LoRa transceiver for both high-speed and long-distance communication. The module targets applications such as smart agriculture, remote meter reading, industrial monitoring, and outdoor long-range wireless control systems. The module measures 18 × 15 × 2.3 mm, making it suitable for space-constrained systems and compact embedded designs. M5Stack has also added an SGM13005L4 low-noise amplifier (LNA) to improve reception performance, along with a PI4IOE5V6408 I/O expander that manages the LoRa control signals without using too many of the ESP32-C6’s GPIO pins. M5Stamp C6LoRa specifications: SoC – Espressif Systems ESP32-C6 CPU Single-core 32-bit RISC-V clocked up to 160 MHz Low-power RISC-V core @ up to 20 MHz Memory/Storage – 512KB SRAM, 320KB ROM Wireless – WiFi 6, BLE 5.3, 802.15.4 (See wireless section) Storage – 16 MB external NOR flash […]

SayoDevice O3C 3-Key Hall-effect keypad boasts 8,000Hz polling rate for playing rhythm games

While searching for new products on AliExpress, I came across the SayoDevice OSU O3C, which looks very similar to other macro keyboards such as the 4xMacropad, the LILYGO TTGO T-Encoder, or the T-Keyboard-S3. However, like the TENSTAR T-Display, it sold over 10,000 pieces on Aliexpress. This warranted an investigation, and I found that it is actually a Hall-effect keypad mainly designed for rhythm and single-input games such as osu! and Geometry Dash. The keypad features OUTEMU magnetic Hall-effect switches with rapid trigger support and a customizable actuation point as low as 0.05 mm, for extremely fast and precise keystrokes. The keyboard connects to a PC via a USB 2.0 cable and supports an 8,000 Hz polling rate for low input latency. The device includes a 0.96-inch IPS color display that can show key travel information, key press counts, or custom images and text, and the first line of the screen […]

Dabao board features open-source hardware Baochip-1x RISC-V MCU (Crowdfunding)

An open-source hardware board usually features a closed-source microcontroller or processors, but the Dabao evaluation board goes further with the open-source Boachip-1x MCU, whose RTL files are available. It’s also manufactured in such a way that it is inspectable with the Infra-Red, In Situ (IRIS) technique, so users can look at the silicon and confirm they’ve got the right chip in a non-destructive way. Baochip-1x is a “general-purpose” microcontroller with a 350 MHz Vexriscv RV32-IMAC CPU core, a BIO accelerator for I/Os with four 700MHz PicoRV RV32-EMC CPU cores, 4MB of ReRAM, 2MB SRAM, a USB interface, various other I/Os, and hardware secure elements such as cryptography accelerators, key stores, one-way counters, true random number generation, and hardware attack countermeasures such as glitch sensors and a security mesh. The Dabao board itself is pretty basic with the microcontroller, two 16-pin headers for I/Os, a USB-C port for power and programming, […]
