ESP32-C2 v2.0 wireless SoC adds 20 KB of additional SRAM, 100 KB of extra flash

Espressif ESP32-C2 (ESP8684) has been updated to v2.0 with 20 KB of additional SRAM, 100 KB of extra flash, with some improvements in terms of erase and program performance. The ESP32-C2 was first unveiled in April 2024 with limited details, and launched in October of the same year as the ESP8684 SiP combining ESP32-C2 die with 4MB flash, as well as a few ESP8684 modules and the ESP8684-DevKitM-1 development board. The ESP32-C2 is meant to be a cost-down version of the ESP32-C3 with less RAM and peripherals, and the ESP32-C2 v2.0 slightly improved on that with parts adding X to the name: ESP8684H2X (2MB flash) and ESP8684H4X (4MB flash). Modules and devkit names are also impacted, albeit not shown yet in the screenshot below. The part names had to be updated because chip revision v2.0 and previous chip revisions are not software-compatible, so Espressif had to update the ordering codes […]

LispDeck handheld lisp computer Runs uLisp on Teensy 4.1 with Wi-Fi, LoRa, and two screens

Designed by Hartmut Graw, the LispDeck is a Handheld Lisp computer built around the Teensy 4.1 microcontroller for Lisp programming on the go. It features a dual-screen setup with a 5-inch touchscreen and, a secondary ST77350-based TFT display. It also has an Adafruit RFM96 radio module, an ESP8266 Wi-Fi module, a rotary encoder, an SD card for storage, and a detachable wireless USB keyboard, all housed in a 3D-printed case. Running the uLisp language, it features a standalone Lisp programming environment without needing a PC or tablet. It is an evolution of the LispBox, with a portable and battery-powered design, which also maintains compatibility. Unlike Raspberry Pi-based cyberdecks, the LispDeck is designed for complete control over the system without the complexity of Linux. It is useful for Lisp enthusiasts who want a compact, dedicated computing device that’s fully documented. LispDeck Specifications SoC – NXP i.MX RT1062 via Teensy 4.1 board […]

TouchEye dual round touch display module features Raspberry Pi RP2040 or ESP32-S3 MCU (Crowdfunding)

TouchEye ESP32-S3 or RP2040 dual touch display board

Last December, Debashis wrote about the Waveshare Double Eye LCD module comprised of two round displays that can be useful for robotics or art projects since they can be made to look like googly eyes. The module is designed to be connected to a host MCU via an SPI interface. The TouchEye looks similar but offers larger 1.28-inch round displays (instead of 0.71-inch), and also adds a touch function. Instead of being connected to a host MCU via SPI like the Waveshare model, the TouchEye dual touch display module is a complete board with an onboard MCU that can be either a Raspberry Pi RP2040 or an Espressif ESP32-S3 that also offers WiFi and Bluetooth connectivity. Both boards also feature a USB-C port for power and programming, a microSD card slot, a GPIO breakout connector, and programmable buttons. TouchEye module specifications: MCU (one or the other) Raspberry Pi RP2040 dual-core […]

ESPNowCam library enables ESP32 video camera or data transmission with the ESP-NOW protocol

ESPNowCam ESP-Now library for ESP32 camera board

ESPNowCam is an open-source library for ESP32 camera boards that relies on the ESP-NOW protocol for efficient point-to-point, one-to-many, or many-to-one video or data transmission. ESP32 microcontrollers already support WiFi or Bluetooth connectivity, but the ESP-NOW offers an alternative in scenarios where low latency is required and/or access to a router is not feasible or practical. That’s why we’ve previously seen ESPNOW used in ESP32 drones. As its name implies, the ESPNowCam project leverages the ESP_NOW wireless protocol for ESP32 video cameras, but can also be used for data transmission. ESPNowCam highlights: Transmission modes One transmitter to multiple receivers using the internal ESPNow broadcasting feature (1:N mode) Peer-to-peer (P2P) connections utilizing MAC address targeting (1:1 mode) Multi-sender mode with one receiver (N:1 mode) No need for IPs, routers, or credentials The project was first released in January 2024, but I’ve only noticed it, and it had several iterations since then.
