R9A02G021 is the first microcontroller with Renesas 32-bit RISC-V CPU core design

Renesas R9A02G021 RISC-V MCU

Renesas R9A02G021 is the first MCU group to use the company’s in-house designed 32-bit RISC-V CPU core with 3.27 CoreMark/MHz, RV32I base plus M/A/C/B extensions, and features such as a stack monitor register, a dynamic branch prediction unit, and a JTAG debug interface. Renesas has been making RISC-V chips at least since 2022 with the likes of RZ/Five 64-bit microprocessor and R9A06G150 32-bit voice control ASSP. All those were based on Andes RISC-V cores, but since the company has now designed its own 32-bit core, future Renesas 32-bit RISC-V microcontrollers are all likely to feature the in-house core, starting with the R9A02G021 general-purpose MCU group. Renesas R9A02G021 key features and specifications: RISC-V Core Renesas RISC-V instruction-set architecture (RV32I + MACB + Ziscr, Control and Status Register (CSR) instructions + RISC-V Zifencei Instruction-Fetch Fence) Maximum operating frequency –  48 MHz Debug and Trace – RISC-V External Debug Support cJTAG Debug Port […]

$6.99 Waveshare’s ESP32-C6-Pico Board resembles Raspberry Pi Pico board

Waveshare ESP32 C6 Pico Devlopment Board

Waveshare’s ESP32-C6-Pico and ESP32-C6-Pico-M development boards are equipped with the ESP32-C6-MINI-1 module supporting Wi-Fi 6(802.11ax), Bluetooth 5, Zigbee 3.0, and Thread 1.3, and inspired by the Raspberry Pi Pico form factor. They can be powered either through USB Type-C or an external 5V DC supply connected to the pins. Previously we have written about similar ESP32-C6-based boards like the SparkFun Thing Plus, ePulse Feather C6, and WeAct ESP32-C6 dev board. However, these boards are priced way over the $6.99 that Waveshare is offering. One exception is the DFRobot’s FireBeetle 2 ESP32-C6 board, which cuts costs by using the IC directly instead of the fully shielded ESP32-C6-MINI-1 module. Waveshare’s ESP32-C6-Pico board specifications: Wireless module – ESP32-C6-MINI-1 SoC – ESP32-C6H4 32-bit RISC-V microprocessor up to 160 MHz with 320KB ROM, 512KB HP SRAM, 16KB LP SRAM, 4MB flash Wireless – 2.4 GHz WiFi 6 with Target Wake Time (TWT) support, Bluetooth 5.3 LE and […]

Duo S RISC-V/Arm SBC features Sophgo SG2000 SoC, Ethernet, WiFi 6, and Bluetooth 5 connectivity

Duo S SBC Sophgo SG2000 Ethernet WiFi 6 Bluetooth

Shenzhen MilkV Technology’s Duo S is a tiny SBC based on the 1 GHz Sophgo SG2000 Arm Cortex-A53 and RISC-V SoC with 512MB DDR3 (SiP), Fast Ethernet, WiFi 6, and Bluetooth 5 connectivity, and a switch to select Arm or RISC-V architecture before powering the board. We already had covered SG2002 Arm/RISC-V boards with 256MB RAM, namely the LicheeRV Nano and Duo 256M, but for people needing more memory, the Duo S provides another option that also features two 2-lane MIPI CSI connectors, a USB 2.0 host port, and two 26-pin headers for expansion. Its form factor reminds me of FriendlyELEC’s NanoPi NEO and family powered by Allwinner processors that were introduced a few years ago. Duo S specifications: SoC – SOPHGO SG2000 Main core – 1 GHz 64-bit RISC-V C906 or Arm Cortex-A53 core (selectable) Minor core – 700 MHz 64-bit RISC-V C906 core Low-power core – 25 to […]

SparkFun’s latest GNSS breakout board features u-Blox NEO-F10N L1/L5 dual-band receiver for urban environments

SparkFun GNSS L1/L5 Breakout Board

The SparkFun GNSS L1/L5 Breakout is a standard precision GNSS board with meter-level positional accuracy that features the u-Blox NEO-F10N dual-band module, an SMA antenna connector, and a USB-C port for power and data. As its name implies, the board relies on the L1/L5 bands of the NEO-F10N instead of the more commonly seen L1/L2 bands and delivers better performance in urban environments. That’s because the L5 band falls within the protected ARNS (aeronautical radionavigation service) frequency band leading to less RF interference. SparkFun GNSS L1/L5 Breakout specifications: GNSS u-Blox NEO-F10N module with L1/L5 dual-band GNSS receiver Concurrent Reception of GPS, Galileo, and Beidou Integrated SMA Connector Time to First Fix: 28s (cold), 2s (hot) Max Navigation Rate for Single GNSS Configuration (GPS): 20 Hz Positional Accuracy (GPS) – 1.5m Time Pulse Accuracy – 30ns Operational Limits Max G: ≤ 4G Max Altitude: 80km Max Velocity: 500m/s Supports NMEA, UBX […]
