STMicroelectronics Stellar P3E quad-core Arm Cortex-R52+ automotive MCU features Neural-ART AI accelerator

Stellar P3E AI automotive MCU Block Diagram

STMicroelectronics has introduced the Stellar P3E, the first automotive MCU with an embedded Neural-ART AI accelerator, designed to simplify X-in-1 Electronic Control Units (ECUs) by consolidating powertrain functions like the inverter, on-board charger (OBC), and DC-DC converter into a single module. The MCU enables smart sensing, predictive maintenance, and virtual sensor applications without the cost and complexity of a separate SoC. The microcontroller features four 500 MHz Arm Cortex-R52+ cores with 19.5 MB of xMemory, which is based on phase-change memory (PCM), offering roughly twice the density of embedded flash. The chip integrates multiple ADC channels for precise sensing, high-resolution PWM down to 102 ps for fine motor control, and 10 timer modules for deterministic real-time operation. Connectivity options include Gigabit Ethernet and CAN-XL, for high-speed, low-latency in-vehicle communication. Stellar P3E (SR6P3EC4/SR6P3EC6) specifications: MCU – SR6P3EC4 / SR6P3EC6 CPU Cores – 4x Arm Cortex‑R52+ cores at up to 500 MHz; […]

ESP32 Marauder 5G – Apex 5 module for Flipper Zero combines ESP32-C5, two Sub-GHz radios, nRF24, and GPS

Designed by HoneyHoneyTrading, the ESP32 Marauder 5G – Apex 5 Module is an ESP32-C5-based hacking and penetration testing tool for the Flipper Zero, with dual-band WiFi 6 (2.4GHz and 5GHz), two Sub-GHz radios (868MHz and 433MHz), an NRF24 radio, and a built-in GPS. This new Flipper Zero module can be considered an upgrade from the ESP32 Marauder – Double Barrel 5G, as it does not rely on a dual-chip configuration for 5 GHz operation, leveraging the ESP32-C5 dual-band capabilities instead. A microSD card slot handles storage, and the device can also save data directly to the Flipper Zero’s microSD card. It also features five antennas, including WiFi, Sub-GHz, nRF24, and GPS, along with dedicated LED indicators for the Sub-GHz radios and nRF24 activity. There is also a hardware button to toggle 433 MHz and 868 MHz Sub-GHz operation, a USB-C port, and a side button for power management and firmware […]

Add a tiny desktop monitor to your PC with the ESP32 Desktop Monitor project

While searching AliExpress for new products, I found the TENSTAR T-Display ESP32-D0WD with a 1.14-inch IPS color IPS LCD and 16MB of QSPI flash that’s used by some as a tiny secondary mirrored monitor for their PC. The board appears to be a low-cost alternative to the original LilyGo T-Display, and also integrates a USB-to-TTL converter (CH9102F), a battery charging circuit, a toggle switch, and two user-programmable buttons, which makes it suitable for projects like the NerdMiner and small-scale dashboards for home automation. The hardware does not seem special, yet they sold over 10,000 pieces of the board. After looking into it, the ESP32 Desktop Monitor project is probably the “culprit” for the high sales number, as it transforms the board into a regular monitor, albeit with a tiny 1.14-inch LCD. More on that after the specifications. TENSTAR T-Display Specifications: SoC – Espressif Systems ESP32-D0WDQ6-V3 MCU cores – Dual-core Xtensa LX6 32-bit […]
