ESP32-C6-Bug WiFi 6, Bluetooth LE, and 802.15.4 board takes a PoE Ethernet shield (Crowdfunding)

We’ve already covered a range of ESP32-C6 boards, but none supporting Ethernet and PoE so far, and the ESP32-C6-Bug board brings that to the table thanks to the Esp32-Bug-Eth shield with a W5500 Ethernet chip, an RJ45 jack and a PoE power module. Like other ESP32-C6 devices, the little board supports Wi-Fi 6, Bluetooth LE 5, as well as Thread and Zigbee through its 802.15.4 radio, but it also integrates some other interesting features such as castellated holes for easy soldering on a carrier board and support for LiPo batteries with built-in battery charging and protection circuits. ESP32-C6-Bug board specifications: SoC – ESP32-C6FH4 MCU cores 32-bit RISC-V core @ 160 MHz 32-bit RISC-V core @ 20 MHz low-power coprocessor can run tasks even when the main system is in deep sleep state Memory – 512 KB SRAM Storage – 4 MB Flash Wireless – WiFi 6, Bluetooth LE 5, and […]

Rockchip RK3568-powered ASUS Tinker Board 3N is now available in three variants

The ASUS Tinker board 3 was first unveiled in April 2023 before being renamed as Tinker Board 3N later that year, and the three variants of the Rockchip RK3568 single board computer (SBC) are now available. The standard configuration is the Tinker Board 3N in the commercial temperature range, while the Tinker Board 3N Plus has the same features, except it can operate in the industrial temperature range (-40°C to 85°C). The Tinker Board 3N Lite is a cost-down version in the same form factor, but with a single gigabit Ethernet port without PoE support, no M.2 B-key socket for an NVMe SSD or 4G/5G cellular connectivity, no 16MB SPI flash, fewer serial interfaces, and no CAN Bus. You’ll find a comparison of the specifications for the three variants in the table below. Note the prices above are from Amazon with a 10% discount when applicable. ASUS provides support for […]

Esp32_oscilloscope Arduino firmware turns your ESP32 board into a web-based oscilloscope

Bojan Jurca’s “Esp32_oscilloscope” is an open-source Arduino sketch that can transform an ESP32 board into a web-based oscilloscope that works over WiFi. We had also written about the Scoppy project to turn the Raspberry Pi Pico W into a 2-channel oscilloscope, but there’s no reason the more powerful ESP32-series microcontroller could not be used for the same purpose, and Bojan’s Esp32_oscilloscope project does just that and works with ESP32, ESP32-S2, ESP32-S3 and ESP32-C3 boards using the I2S interface for fast data sampling. The project was initially designed to demonstrate the multitasking abilities of the ESP32 microcontroller with Arduino, but this evolved into an ESP32 oscilloscope firmware. It works both with output/PWM and input signals, digital (0 or 1) and analog (0 to 4095) signals, and the web interface shows up to 736 samples per screen although the sampling rate may not be completely constant all the time. To install it […]

NRFICE is a Bluetooth FPGA board in the Arduino UNO form factor (Crowdfunding)

The NRFICE FPGA is a Bluetooth FPGA board designed for edge computing and IoT applications. It is built upon a combination of the dual-core nRF5340 Bluetooth SoC and the Lattice ICE40UP5K FPGA. The ICE40 UltraPlus is a low-power, high-performance FPGA for edge computing and artificial intelligence projects and the nRF5340 is a Bluetooth 5.3 SoC that supports Bluetooth Low Energy (BLE), Bluetooth Mesh, Thread, NFC, and Zigbee. Through the Nordic nRF5340, NRFICE can load a project directly into the iCE40 FPGA, bypassing the usual extensive toolchain setup. This enables a new class of FPGA development, where bitstreams can be hosted in the cloud, selected by a user on their phone, and loaded wirelessly to the board. It features a built-in J-Link OB for easy debugging and programming without the need for emulator dongles and is similar to the previously covered Segger emPower evaluation board in this regard. This board supports […]
