Lite3DP Gen 2 is a tiny, open-source resin 3D printer (Crowdfunding)

The Lite3DP Gen 2 3D Printer builds on the success of its predecessor. With a new and improved design, an ESP32 microcontroller replacing the Arduino Pro Mini, and several other improvements, the Lite3DP Gen 2 is well-suited for making small, detailed resin prints. It is slightly bulkier than the Lite 3DP S1 3D printer but is still compact enough to fit into a bag. Gen 2 has been designed to maintain backward compatibility with the older model, and owners of existing Lite3DP printers can use the Gen 2 dev kit to upgrade their printers. The resin 3D printer is completely open-source (firmware, hardware, and software), and you can use the schematics, Gerber files, code, and other resources hosted in the GitHub repository to build a different kind of mSLA resin printer. Lite3DP Gen 2 key features & specifications: Electronics – All-in-one PCB with ESP32 microcontroller, high-res LCD, an ultra-silent TMC2209 […]

Sparkfun's latest development board puts Espressif ESP32-PICO-MINI-02 on a compact Arduino Pro Mini footprint. It also includes an onboard QWICC connector for easy interfacing with a wide range of sensors and peripherals,

SparkFun’s latest development board, the ESP32 Qwiic Pro Mini, puts the Espressif ESP32-PICO-MINI-02 on a compact Arduino Pro Mini footprint. It also includes an onboard QWICC connector for easy interfacing with a wide range of sensors and peripherals. We have already covered other Sparkfun dev boards like DataLogger IoT, Datalogger IoT – 9DoF, and SparkFun Thing Plus Matter you can check those out if interested. Like any other ESP32 board, this also uses an ESP32 microcontroller which features a 32-bit dual-core processor, 520kB of SRAM, 2MB of PSRAM, 8MB of flash memory, and 16 kB of additional SRAM in its RTC. It supports Bluetooth 4.2 and BLE and has ADC and DAC, touch detection, PWM, TWAI, Ethernet MAC, UART, SPI, SDIO, I2C, and I2S interfaces. As reported in a Hackster article, the board also features a Qwiic Connector for solderless connections to sensor boards and add-ons, positioned at a 90-degree angle […]

Microflex MCUs – Tiny USB development boards based on ESP32-S3, ESP32-S2, ESP32-C3, ESP32-C6, or Raspberry Pi RP2040 (Crowdfunding)

Microflex MCU board with ESP32 and RP2040 microcontrollers

SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]

RoomSense IQ – An ESP32-S3 modular room monitor with mmWave radar presence detection (Crowdfunding)

RoomSense IQ is a modular room monitor for presence-based home automation based on the ESP32-S3 module with Bluetooth Wi-Fi connectivity. It uses physical presence detection to automate your smart home devices. It comes with multiple sensors that can be used to detect human activity and track ambient light, temperature, and humidity levels. It uses mmWave radar technology to determine when rooms are empty and when they are occupied. It also features built-in temperature, humidity, and light sensors for indoor climate monitoring and control. Rather than relying on schedules, or voice detection, RoomSense IQ triggers automations or alerts based on whether people are in a room or not. It is therefore possible to set it to automatically turn off lights or air conditioning in rooms that are empty to save on energy. In addition, the device offers distance to target measurement that can be adjusted to trigger certain actions. RoomSense IQ […]

ESP32 may soon get an open-source WiFi MAC layer

Most, if not all, WiFi hardware relies on closed-source binary blobs including ESP32 wireless MCU, but there’s now work underway to reverse engineer a WiFi MAC layer for the ESP32 to make it a truly open-source platform. Espressif ESP32 wireless microcontrollers already have an open-source framework (ESP-IDF) and toolchain, people can customize the code to some extent, but this excludes the wireless bits (Wi-Fi, Bluetooth, low-level RF functions) that are distributed as closed-source precompiled libraries integrated into the firmware. There were some efforts to provide an open-source stack for the BL602 chip but it never went anywhere, and the ESP32 may become the first target with an open-source driver without any blobs, excluding FPGA-based projects such as OpenWiFi. The early-stage implementation currently supports the following features: Sending WiFi frames Receiving WiFi frames Send an ACK packet as a reply to packets that are sent to the ESP32 Connect to an […]
