$14 development board features GUITION ESP32-P4 + ESP32-C6 module

JC ESP32P4 M3 DEV ESP32 P4 evolution board

While searching Aliexpress for new products, I found out about the JC-ESP32P4-M3-DEV from the Maker Go AliExpress store, another ESP32-P4 development board with features very similar to the ESP32-P4-Function-EV-Board or the Wireless Tag WT99P4C5-S1 board, but built around the GUITION JC-ESP32P4-M3-C6 module, which combines ESP32-P4 and ESP32-C6 into a single package instead of having separate chips or modules on most other designs. Features include 32MB of PSRAM and 16MB of flash on the GUITION module, a microSD card slot for storage, a built-in microphone, speaker output via the ES8311 audio codec, and an audio amplifier. The board also offers a 10/100Mbps Ethernet RJ45 port, an RS-485 terminal block, a GPIO header, and expansion connectors for both the ESP32-P4 and ESP32-C6 chips. Additionally, there are three USB ports: two USB-C and one USB-A for power, data, and debugging, along with a few buttons and LEDs. JC-ESP32P4-M3-DEV evolution board specifications: Core module […]

Renesas RA2T1 low-power Cortex-M23 MCUs target BLDC/PMSM motor applications

Renesas RA2T1 microcontroller (MCU) group

Renesas has recently launched the RA2T1 group of low-power motor control MCUs, built around a 64 MHz Arm Cortex-M23, for low-cost single-motor applications like power tools, fans, and home appliances. Designed for Brushless DC Electric Motors (BLDC) and Permanent Magnet Synchronous Motors (PMSM), the RA2T1 supports both trapezoidal and FOC control techniques, thanks to its integrated 3-channel Sample and Hold (S&H) circuits that enable accurate 3-phase current detection. It also includes PWM shutdown features and various analog and digital peripherals in compact packages as small as 4×4 mm QFN. Previously, Renesas introduced the RA8T1, also a motor control MCU based on the Cortex-M85 core with Helium instructions and DSP extensions. Ideal for AI-enhanced motor control in industrial and robotics applications. Around the same time, Infineon launched the PSOC Control C3x series, with real-time motor control and security features along with fast ADCs, high-resolution PWM, and PSA Level 2 compliance.
