Makerfabs MaTouch ESP32-P4 10.1-inch HMI display features 4G LTE and Ethernet connectivity, a 2MP camera
Makerfabs MaTouch ESP32-P4 TFTTouch 10.1 MIPI with 4G LTE is an ESP32-P4 + ESP32-C6-based display development platform for HMI edge AI, and connected embedded applications. The development board features a 10.1-inch IPS LCD, very similar to those of Seeed Studio’s reTerminal D1001, Waveshare ESP32-P4-WIFI6-Touch-LCD, and CrowPanel Advanced 7-inch displays. However, what makes it unique compared to other devices is that it also features a SIM7670G 4G LTE modem with a SIM card slot, an RJ45 Ethernet jack, and a 2MP camera. The HMI display also comes with microphone and speaker connectors, a microSD card slot, various USB interfaces, lithium battery support, and two 2.54 mm pitch GPIO expansion headers exposing UART, I2C, SPI, and other peripheral interfaces. All these features make it suitable for HMI, edge AI, and connected embedded applications.

OpenC6 BIOS project brings PC-like firmware to ESP32-C6 MCU with network boot and OTA update support
OpenC6 BIOS is an open-source project by Rompass that takes a different approach to MCU development. It adds a BIOS-like system to the ESP32-C6, so the system part and application code can run separately rather than being combined into a single firmware image. In traditional development, hardware setup, networking, and application code are combined into a single firmware image. But the OpenC6 BIOS operates differently: it runs as the base system on the ESP32-C6 and handles hardware initialization and system functions. Instead of flashing a full application each time, it can load small payload programs separately. These payloads can run from RAM or flash (XIP) and use system functions through a simple Application Binary Interface (ABI), without needing the full firmware. In some ways, it operates like AkiraOS, but with a BIOS-like interface. Key features of the OpenC6 BIOS architecture: Dynamic CPU scaling – Adjusts CPU frequency based on load
SCINTIX P4 ESP32-P4 Compute Module works with (some) Raspberry Pi CM4/CM5 carrier boards (Crowdfunding)
SCINTIX P4 is an ESP32-P4 RISC-V Compute Module with an ESP32-C6 for wireless connectivity that's compatible with Raspberry Pi CM4/CM5 carrier boards, at least partially. It should be the first MCU-based system-on-module in Raspberry Pi CM4/CM5 form factor, and RELOC says the SCINTIX P4 gives access to displays, cameras, Ethernet, USB, and all the peripherals the ESP32-P4 exposes when connected to a carrier board. It can also be programmed in standalone mode through its built-in USB Type-C port. SCINTIX P4 (RM-CMP4) specifications: SoC - Espressif Systems ESP32-P4NRW32X CPU Dual-core RISC-V @ 400 MHz with AI instruction extensions and single-precision FPU Single-core RISC-V LP (low-power) MCU @ up to 40 MHz GPU - 2D Pixel Processing Accelerator (PPA) VPU - H.264 and JPEG codecs support Memory - 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM, 32MB PSRAM Storage - 128 KB HP ROM, 16 KB LP ROM Storage
Espressif ESP32-E22 WiFi 6E module gets Wi-Fi CERTIFIED certificate, an open-source WiFi and Bluetooth Linux drivers
The ESP32-E22 tri-band Wi-Fi 6E and Bluetooth 5.4 module has received a Wi-Fi CERTIFIED certificate from the Wi-Fi Alliance, and Espressif has also released WiFi and Bluetooth Linux drivers for the chip. The ESP32-E22 was first unveiled at CES 2026 with a dual-core RISC-V processor clocked at up to 500 MHz, 1MB RAM, tri-band WiFi 6E tested up to 2.1 Gbps with iperf, and dual-mode Bluetooth 5.4/6.0. While it also features 41 GPIO pins, it's not mainly designed for IoT projects, but instead targets host-based wireless systems needing WiFi 6E / Bluetooth 5.4 connectivity through PCIe 2.0 or SDIO interfaces. In other words, the ESP32-E22 will likely show on M.2 modules, competing against similar products from MediaTek and Intel. Espressif has not said which module was tested for the Wi-Fi CERTIFIED certificate, but I suspect it should be the upcoming ESP32-E22-M2-1 M.2 module listed on the company's website. From the certificate,
M5Stack Capsule Kit v1.1- A Battery-powered ESP32-S3 IoT controller with IMU sensor, MEMS microphone, and IR transmitter
M5Stack Capsule v1.1 is a Stamp-S3A-based IoT controller with a microSD card slot, several sensors (6-axis IMU, microphone), an IR transmitter, a built-in 250 mAh battery, a few buttons, a buzzer, an RTC, and expansion capabilities through GPIO headers and a Grove connector. It's an upgrade to the earlier Capsule based on the Stamp-S3 module. The new version still features an ESP32-S3 WiFi and Bluetooth microcontroller, 8MB flash, a USB-C port, and a few GPIOs, but benefits from the Stamp-S3A improvements, including an optimized antenna design and lower power consumption. We never had a look at the Capsule before, so let's do it now.

Bare-metal MSX2+ Emulator for ESP32-S3 offers custom LCD_CAM VGA implementation & Z80 optimizations
Ivan Svarkovsky's S3-MSX-PC open-source project implements a bare-metal MSX2+ emulator running on an ESP32-S3 microcontroller and outputting 64-color VGA via a simple R-2R resistor ladder. It's a fork of the Retro-Go emulator for ODROID-GO and other ESP32 devices, but with various optimizations. It was tested on an off-the-shelf ESP32-S3 board with one core handling the game logic and the other video and audio output. VGA is implemented through a clever resistor network that converts digital data into an analog signal that any old monitor understands, while audio relies on Sigma-Delta modulation with a multi-stage PDM filter. The USB host port on the board allows for the connection of a keyboard. S3-MSX-PC firmware highlights: Emulation Core - fMSX 6.0 — Full MSX1 / MSX2 / MSX2+ support Video Output VGA 640×480@60Hz, 16-bit parallel RGB via LCD_CAM Color Depth - 64 colors (2 bits per channel: R, G, B) Audio - PDM Stereo
