Duo 256M is a compact SBC based on SG2002 multi-architecture SoC

Duo 256M is a small board powered by SOPHGO SG2002 multi-architecture Arm/RISC-V/8051 SoC with 256MB of on-chip RAM and a 1 TOPS NPU, a microSD card for storage, a camera connector, a USB-C port for power and programming, and two headers for GPIO expansion. We covered the SOPHGO SG2002 (and SG2000) Arm+RISC-V+8051 AI SoC earlier this month saying a couple of boards were expected very soon. We’ve already covered Sipeed LicheeRV Nano with optional Ethernet or WiFi 6, and now we’ll look at the Duo 256M designed by Milk-V Technology in more detail since it’s available now. Duo 256M specifications: SoC – SOPHGO SG2002 Main core – 1GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (selectable) Minor core – 700MHz 64-bit RISC-V C906 core Low-power core – 25 to 300MHz 8051 MCU core NPU – 1 TOPS INT8, supports BF16 Integrated 256MB DDR3 (SiP) Storage MicroSD card slot 32Gbit NAND […]

Ovrdrive USB is an open-source, privacy-oriented USB flash drive that can self-destruct (Crowdfunding)

We have previously covered the Tillitis Tkey, an open-source security key in a USB-C case but the Ovrdrive USB stick is not a security key. It is a simple, plain USB flash drive with a special security feature. It will appear completely blank unless you plug this drive in three times in quick succession. The Ovrdrive flash drive is aimed at journalists in repressive areas and security researchers but may be useful to other security and open-source hardware enthusiasts. As for how it works, the Ovrdrive has two identical circuits connected to the ATtiny24A microcontroller that controls the rapid plug-in functionality. When the flash is plugged in, the microcontroller powers on, and the CHG1 node goes high, charging C3 through D2. The pin will remain high for a while and then slowly discharge via R1 and body resistance. C3 and the identical C14 will remain high through power cycling/a quick […]

CERBERUS 2100 is a BASIC-programmable educational board with Z80 and 6502 8-bit CPUs

Olimex has just announced the launch of the CERBERUS 2100 open-source hardware, educational, multi-processor 8-bit computer with both Z80 and 6502 CPUs, as well as a Microchip AVR processor serving as an I/O controller. The CERBERUS 2100 features several CPLD and is fully programmable from the lowest level (individual gates and flip-flops) up to BASIC interpreters running on the Z80 and 6502 CPUs. Olimex did not design this themselves as the hardware design is from Bernardo Kastrup (aka TheByteAttic), while BASIC interpreters were written by Alexander Sharikhin (6502) and Dean Belfield (Z80). CERBERUS 2100 specifications: Processors Zilog Z80 8-bit microprocessor at 4 or 8 MHz (user selectable) Western Design Center W65C02S 8-bit microprocessor at 4 or 8 MHz (user selectable) “FAT-CAT” (Custom ATmega328pb) Microchip 8-bit AVR ATMega328PB microcontroller at 16 MHz CPLDs (ATF1508AS-7AX100) FAT-SCUNK (Scan CoUNter and clocK) and FAT-CAVIA (ChAracter Video Adapter) for video circuit connected to a 25.175 […]

Microchip introduces PIC16F13145 Series MCUs with customizable logic

Microchip New MCU with Configurable Logic Block

Microchip recently introduced the PIC16F13145 series of 8-bit MCUs featuring a Configurable Logic Block (CLB). This allows users to create custom hardware-based logic functions within the MCU. This approach lowers the BOM costs and boosts performance. Last year, we saw Microchip introduce PIC32CZ Arm MCU with a Hardware Security Module (HSM) and before that, we saw they launched LAN8650/LAN8651 10BASE-T1S single-pair Ethernet Controllers. Feel free to check those out if you are interested in the topics. Microchip PIC16F13145 Series MCU Specification: 32MHz PIC16 CPU core Up to 1KB User SRAM for application data Up to 14KB Flash memory with code protection features CLB Capabilities: Up to 32 basic logic elements – AND/OR/NAND/NOR gates, buffers/inverting buffers, D/JK flip-flops, multiplexers, 4-input LUT Dynamic configuration for on-the-fly changes Tri-state logic capability Inputs/outputs from software, I/O pins, and PIC® peripherals (ADC, PWM, DAC, etc.) Less than 6 ns BLE propagation delay at 5.5V (typical) […]
