Lua-programmable ELM11-Feather board puts Gowin GW1NR FPGA into Feather form factor (Crowdfunding)

BrisbaneSilicon ELM11-Feather is a “microcontroller” board based on a Gowin GW1NR FPGA that is natively programmable in Lua, C, SystemVerilog, and VHDL. Compatible with the Adafruit Feather form factor, the board features GPIO headers, a built-in debugger, a USB-C port for power and programming, and a 2-pin header for a LiPo battery. The company calls it a microcontroller board because the FPGA runs a PicoRV32 MCU softcore at up to 75 MHz with 1MB RAM and 8MB flash, programmable with Lua, and the user can also customize hardware layers with RTL code using the remaining FPGA fabric. ELM11-Feather specifications: FPGA – Gowin GW1NR-LV9 FPGA from the GW1NR-9 family 8K LUTs 8,640 logical units (LUTs) 6,480 flip-flop 17,280 bits shadow SRAM (SSRAM) 486 Kbit block SRAM (BSRAM) 64 Mbit (8MB) PSRAM 608 Kbit user flash 2x PLL Up to 276x user I/O USB – 1x USB Type-C port for power and […]

Makerfabs MaUWB for Home Assistant – An ESP32-S3 UWB module with PoE and enclosure

Makerfabs MaUWB for Home Assistant is an ESP32-S3-based Ultra-Wideband (UWB) module designed for indoor positioning and Real-Time Location Systems (RTLS). It runs ESPHome for Home Assistant integration, enabling it to be used as part of a UWB-based positioning system to track tagged devices in homes, offices, and other indoor environments. The module combines an ESP32-S3 with a MaUWB UWB module based on the Qorvo DW3000, featuring a PA/LNA for long-range ranging. Compared to the earlier ESP32-S3 version, it drops the OLED and adds a WIZnet W5500 Ethernet controller that supports PoE. The module also supports Wi-Fi 4 and Bluetooth 5.0, and comes in an enclosure for fixed installations. Makerfabs MaUWB for Home Assistant specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM; 8MB PSRAM Wireless – WiFi 4 and Bluetooth LE 5 […]
