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
PZSDR P047 RF-ADC and RF-DAC high-end SDR board is based on AMD Zynq UltraScale+ ZU47DR RFSoC (Crowdfunding)
PZSDR P047 RF-ADC and RF-DAC software-defined radio (SDR) board is based on AMD Zynq UltraScale+ ZU47DR RFSoC with a quad-core Cortex-A53 processor, a dual-core Cortex-R5F real-time CPU, FPGA fabric, eight RF ADCs, and eight RF DACs. The board features 6GB of DDR4 memory (4GB for PS, 2GB for PL), 8 GB eMMC flash, and 512 Mbit QSPI flash, plus microSD card and M.2 NVMe sockets for storage, a mini DP video output, a Gigabit Ethernet RJ45 port, two 100 Gbps QSFP28 cages, a USB 3.0 port, plus JTAG and serial debug interfaces, and a 32-pin IO header. It makes use of all RF channels of the RFSoC with 8 receiver and 8 transmitter connectors, plus various clock inputs. The company says the PZSDR P047 is ideal for advanced MIMO wireless applications such as cellular and shortwave communication.

I just received, assembled, and configured the Anavi 12-key Macro Keyboard. There is a python file that shows up on a USB filesystem that appears when the keyboard is plugged in, which is easy to configure to produce any macro keys. I'm using it to control OBS hotkey scripts for live streaming. I highly recommend this keyboard.

Modos Flow – An FPGA-based 13.3-inch USB-C touchscreen e-paper monitor (Crowdfunding)
Modos Flow is a paper-like, 13.3-inch USB Type-C touchscreen monochrome or color monitor that builds upon the Modos Paper devkit introduced last year with an AMD/Xilinx Spartan-6 LX16 FPGA and STMicro STM32H750 Arm Cortex-M7 microcontroller. The main difference is that the Modos Flow is more like a consumer product with a full enclosure, a touchscreen, and optional stylus support, 4096-color e-paper display, and frontlight. Modos Flow specifications: FPGA – AMD Xilinx Spartan-6 LX16 FPGA running Caster gateware like the earlier devkit MCU – STMicro STM32H750 Arm Cortex-M7 microcontroller for USB communication, firmware upgrades, and standalone applications. Display 13.3-inch e-paper display with 3200 x 2400 resolution Refresh rate - 60 Hz with additional power, 40 Hz via a single USB-C cable Monochrome or 4096 colors/16 levels of grayscale Touchscreen support Optimized display modes for reading, browsing, watching, and writing Amber-tinted frontlight (color model only) Video Input - USB Type-C DisplayPort Alt-Mode with
Prunt Board 3 3D printer control board offers smoother and quieter operation (Crowdfunding)
Prunt Board 3 is a 3D printer control board with six TMC2240 stepper drivers, two 15A heater outputs, four fan outputs, four thermistor inputs, and four endstop inputs that is designed to offer smoother and quieter operation. The hardware is said to offer better ESD protection than boards such as the Duet 3 Mini 5+ or BTT SKR 3 EZ and supports hardware-accelerated step generation, but the magic happens with the Prunt firmware and associated server, which enable a 31-phase velocity profile for smoother operation and higher-quality prints compared to boards running Klipper or Marlin firmware. Let's have a look at the hardware first. Prunt Board 3 specifications: 6x TMC2240 stepper drivers, all capable of running at 3A with minimal airflow 2x 15A heater outputs with short circuit protection (1.3 µs response time) Fan outputs 4x fan outputs supporting 2, 3, and 4-pin fans, all up to 2A with short
MiciMike’s open-source drop-in PCB converts Google Home Mini into a local voice assistant (Crowdfunding)
The MiciMike Home Mini Drop-In PCB is an open-source replacement mainboard designed to convert a 1st Gen Google Home Mini into a fully local, privacy-focused voice assistant running Home Assistant Voice. Built around an ESP32-S3 MCU and an XMOS XU316 audio processor, it removes cloud dependencies without any case modifications or soldering. The board offers on-device wake word detection, echo cancellation, and noise suppression via two MEMS microphones, and comes pre-flashed with ESPHome for easy Home Assistant integration. The PCBA fully supports local voice processing, optional cloud LLM integration, media playback, and Snapcast. It's released as open hardware under the CERN-OHL-S v2 license, with complete design files available, making it suitable for privacy-focused smart-home automation, DIY voice assistants, and hardware-reuse projects. MiciMike Home Mini Drop-In PCB specifications: Compatibility – Google Home Mini 1st generation Wireless MCU – Espressif Systems ESP32-S3 CPU - Dual-core Xtensa LX7 microcontroller @ up to 240
