Seon Rozenblum, better known as Unexpected Maker, has launched NANOS3  a development board that claims to be the world’s smallest, fully-featured ESP32-S3 module! This new module packs all the peripherals, and wireless connectivity features of an ESP32-S3 while being even smaller than the TinyPICO Nano. The module features two variants one with an onboard 3D antenna and the other with an u.FL connector. Previously we have written about TinyS3, FeatherS3, and ProS3 boards from Unexpected Maker we have also covered many unique ESP32-S3 boards like the ESP32-S3 PowerFeather Board with solar input, the Waveshare ESP32-S3-Relay-6CH, the ESP32-S3 4G dev boards and more feel free to check those out if you are interested in ESP32 boards with advanced features.

Nuvoton has recently announced their M433 Series MCUs (M433LE8AE and M433SE8AE) along with the NuMaker-M433SE development board. Nuvoton is calling this the “M433 CAN/USB FS OTG” Series, featuring an Arm Cortex-M4F core with DSP and FPU extensions. The MCU is clocked at 144 MHz and consumes 350 nA in deep power-down mode, making it ideal for battery-operated IoT, industrial, and consumer applications. This is not the first Nuvoton MCU we have written about. In recent months, we have seen Nuvoton release the NuMicro M091 Series, the Nuvoton MA35H0 – a cost-optimized MPU, and other dev boards and MCUs.

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 [...]

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 [...]
