ESP32-S3 based Arduino Nano ESP32 board supports Arduino and MicroPython programming

The Arduino Nano ESP32 is an ESP32-S3-based WiFi and Bluetooth microcontroller board designed for IoT applications for hobbyists and enterprise use cases. The new Nano board comes with 8 MB PSRAM and 16 MB flash storage and can be programmed with either the Arduino or MicroPython languages. It’s not the first ESP32 board from Arduino, as the Nano RP2040 Connect pairs a Raspberry Pi RP2040 MCU with an ESP32 module from u-Blox and the just-released Arduino UNO R4 WiFi marries a Renesas RA4M1 Arm Cortex-M33 MCU with an ESP32-S3-MINI-1 module. But the Arduino Nano ESP32 is different since it’s the first ESP32 board from Arduino where the Espressif chip is the only microcontroller onboard and handles both wireless connectivity and GPIOs. Arduino Nano ESP32 specifications: Wireless module – u-Blox NORA-W106-10B with MCU – ESP32-S3 dual-core Xtensa LX7 microcontroller @ up to 240 MHz with vector extensions, 512KB SRAM, 384KB ROM, […]

The Bee Data Logger ESP32-S3 board comes with RTC, microSD slot, and two Qwiic connectors for sensors

A few months ago, SparkFun released the “Datalogger IoT – 9DoF” no-code platform based on ESP32 with some built-in sensors, a microSD card, and two Qwiic connectors to add sensors in order to perform data logging with minimal to no coding. Smart Bee Designs looks to have shrunk the design, removing the built-in sensors in the processor, with the Bee data logger ESP32-S3 board that offers most of the same features plus a built-in DS3231 RTC and back battery for timekeeping, and the ability to leverage the vector extension in the ESP32-S3 for machine learning applications. Bee data logger specifications: Wireless module – Espressif Systems ESP32-S3-MINI-1 module CPU – ESP32-S3 dual-core Xtensa LX7 microcontroller with vector extensions with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity Storage – 8MB of QSPI flash PCB antenna Storage – MicroSD card slot up to 16GB capacity USB – 1x USB Type-C port […]

An ESP32-S3 board for vending machines with RS485, microSD card slot, optional cellular mPCIe module

LILYGO T-Vending is an ESP32-S3 WiFi and Bluetooth IoT board designed for vending machines with an RS485 terminal block, a microSD card slot, and support for an optional cellular mPCIe module. As I understand the board is connected to the vending machine through the RS485 terminal block to control vend motors (potentially via an additional board to control multiple motors) and a 10-pin connector for power (12V/24V), signals to/from a coin mechanism and other parts. The board also adds a Grove connector and an unpopulated 12-pin GPIO header for expansion. T-Vending specifications: ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Wireless 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity (ESP32-S3) Optional T-PCIe 4G LTE […]

WeAct launches $6 ESP32-C6 development board, ESP-IDF 5.1 framework released

As expected, Espressif has just released the ESP-IDF 5.1 framework with ESP32-C6 and ESP32-H2 support, so more ESP32-C6 boards should become available, and after Olimex ESP32-C6-EVB launched earlier this week, we’ve noticed WeAct had introduced a low-cost ESP32-C6 development board that sells for just $6.43 plus shipping a few weeks ago. WeAct ESP32-C6 board The WeAct board offers 2.4 GHz WiFi 6, Bluetooth LE 5.0., and Zigbee/Thread connectivity through the ESP32-C6-WROOM-1 module, two USB-C ports, two 16-pin headers for GPIOs, and if it looks familiar, it’s because it closely follows the design of the official ESP32-C6-DevKitC-1 development kit, albeit with some small modifications. WeAct ESP32-C6 board specifications: Wireless module – ESP32-C6-WROOM-1 with ESP32-C6 single-core 32-bit RISC-V clocked up to 160 MHz, with 320KB ROM, 512KB SRAM, low-power RISC-V core @ up to 20 MHz Wireless – 2.4 GHz WiFi 6, Bluetooth 5.0 LE, 802.15.4 radio for Zigbee 3.0 and Thread.

Arduino UNO R4 Minima and WiFi boards launched for $20 and $27.50

Arduino UNO R4 Minima and WiFi boards powered by a Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller and equipped with an optional ESP32-S3 WiFI & BLE module are now available for respectively $20 (18 Euros) and $27.50 (25 Euros) on the Arduino store. The Arduino UNO R4 Renesas RA4M1 board was initially unveiled during Arduino Day with most details, but not everything as the company had hidden one part of the board which we now know is for a 12×8 LED matrix and a Qwiic connector for expansion present on the UNO R4 WiFi only. Arduino UNO R4 specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core Xtensa LX7 microcontroller with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity, PCB antenna Display (UNO R4 WiFi only) – 12×8 LED […]

Olimex ESP32-C6-EVB supports WiFi 6, BLE, Zigbee, comes with four relays, four opto-isolated inputs

Olimex ESP32-C6-EVB is an open-source hardware board based on an ESP32-C6 wireless module with 2.4 GHz WiFi 6, Bluetooth LE, and Zigbee connectivity, and offering four relays and four opto-isolated inputs, as well as further expansion via two UEXT connector. So far we had a limited amount of third-party ESP32-C6 boards, with Espressif making their own module and development board available in January, and 01Space launching a tiny ESP32-C6 board in April, a time when a lot of software work was still needed. But the ESP-IDF v5.1 with ESP32-C6 support is nearing release (now RC2), and the Olimex board may mark the start of greater availability of ESP32-C6 hardware with stable/usable firmware. ESP32-C6-EVB specifications: Wireless module – ESP32-C6-WROOM-1-N4 module with Espressif Systems ESP32-C6 single core 32-bit RISC-V processor @ 160 MHz with 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support, Bluetooth LE 5.0, and 802.15.4 radio for […]
