UDOO KEY ESP32 & RP2040 board launched for $4 (Crowdfunding)

UDOO is known for its x86 boards that embed an Arduino compatible MCU, but the UDOO KEY is different, as it does without an Intel or AMD processor, and instead, combines Raspberry Pi RP2040 microcontroller with Espressif ESP32 WiFi & Bluetooth WiSoC. As we noted in the past combining Raspberry Pi Pico/RP2040 with ESP32 does not make a lot of sense in most cases, but here’s the UDOO KEY will be offered for just $4 for the first 1,000 units, so they’ll basically throw the ESP32 for free since it’s the same price as one Raspberry Pi Pico, before eventually selling the device for $20. UDOO KEY specifications: MCU- Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 133 MHz with 264KB of on-chip SRAM Storage – 8MB QSPI Flash for RP2040 Wireless module – ESP32-WROVER-E with ESP32-D0WD-V3 dual-core WiFi + Bluetooth SoC, 16MB SPI flash, and 8MB PSRAM Sensor – […]

Build a LoRaWAN weighing scale with TTGO T-Weigh ESP32 board, HX711 modules

Ever wanted to build your own LoRaWAN connected weighing scale? Me neither, but apparently those types of products already exist for logistics and inventory management, and LilyGO’s latest ESP32 board – the TTGO T-Weigh – is designed for this exact purpose with a Semtech SX1272 based LoRa module, and four HX711 24-bit ADC chips. The board can handle up to four scales that transfer weight data over WiFi, Bluetooth or LoRaWAN, and should be useful in applications that require weighting goods or products where there are limited connectivity options including logistics, farming. TTGO T-Weigh specifications: Wireless modules TTGO T-Micro32 module based on ESP32-PICO-D4 SiP with ESP32 dual-core processor, 4MB SPI flash, 2.4 GHz WiFi 4 and Bluetooth 4.2/5.x TTGO LORA32 module based on Semtech SX1262 transceiver (EU868/US915)with -22 dBm Tx power, -148 dBm sensitivity, up to 62.5 kbps LoRa bitrate, up to 300 kbps FSK bitrate Antennas WiFi/Bluetooth – Ceramic […]

Portenta H7 Lite cost-optimized Arduino Pro board drops WiFi, USB-C video output, NXP secure element

Arduino Portenta H7 Lite is a cost-down version of Portenta H7 STM32H7 that shaves off a little over $30 of the Arduino Pro board by doing without a wireless module nor USB-C video output and opting for a lower cost Microchip ATECC608 secure element. Arduino says the new board provides a cost-optimized solution for companies developing high-end industrial machinery, laboratory equipment, computer vision, PLCs, robotics controllers, and mission-critical devices. Arduino Portenta H7 Lite specifications (with differences in bold or strikethrough): Microcontroller – STMicro STM32H747XI Cortex-M7 @ 480 MHz + M4 @ 200 MHz MCU with 2MB dual-bank Flash memory, 1 MB RAM, Chrom-ART graphical hardware accelerator System Memory – 2MB SDRAM (upgradeable up to 64MB) Storage – 16MB QSPI NOR Flash (Upgradeable up to 128MB) Connectivity 2.4GHz WiFi 802.11b/g/n up to 65 Mbps and Bluetooth 5.1 BR/EDR/LE via Murata 1DX module On-board 10/100M PHY Video I/F – MIPI DSI & […]

ESP32 Arduino 2.0.0 release adds ESP32-C3 and ESP32-S2 support

As just noted in my article about LILYGO T-32C3 module, the ESP32 Arduino 2.0.0 release happened a few days ago adding ESP32-C3 and ESP32-S2 support to the Arduino IDE. But the news probably warrants its own post and it is a major release of the Arduino code for ESP32 that also includes other new features and changes namely: Upload over USB CDC. Support for the KSZ8081 Ethernet PHY. LittleFS update for partition label and multiple partitions. Added support for RainMaker. BLE 5 features for ESP32-C3 (ESP32-S3 ready). ESPTOOL update. Added 802.11mc WiFi RTT FTM (Fine Time Measurement) support. Online Documentation added (somehow it requires a login to Readthedocs). USB MSC (Mass Storage) and HID support (ESP32-S2 only). UART refactoring (SerialHardware). New examples, boards added, bugs fixed. You can find a more detailed changelog, including the exact files changes in the source code, on Github. If we want to give it […]
