ESP-FLY DIY Kit is a tiny ESP32-S3-based DIY micro drone kit

ESP-FLY DIY kit is a miniature DIY drone kit based on Seeed Studio’s XIAO ESP32-S3 board that was initially introduced as a DIY project on Instructables by Max Imagination, but is now available as a complete kit for $59.99 on Seeed Studio. It’s certainly not the first ESP32 drone, but the ESP-FLY drone must be the smallest, as the miniature (67 x 67 x 31mm) quadcopter design allows users to store into any pocket or small boxes. It’s mainly designed for STEM education, hobbyist DIY Projects, and indoor flight practice. ESP-FLY drone kit key features and specifications: Main Controller – Seeed Studio XIAO ESP32-S3 board Wireless MCU – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller @ 240 MHz System Memory – 512KB SRAM, 8MB PSRAM Wireless – Wi-Fi 4 & Bluetooth 5.0 dual-mode (Classic + BLE) connectivity Storage – 8MB SPI flash Antenna – External u.FL antenna USB […]

Flash Bee – An ESP32-C3-based DIY handheld lightning detector

Flash Bee is an easy-to-make DIY handheld lightning detector based on off-the-shelf parts such as the XIAO ESP32C3 board and the Round Display for XIAO, as well as a 3D-printed enclosure. The design relies on the AMS AS3935 Franklin lightning sensor that’s been around for years, and found in kits like Sparkfun’s Arduino IoT weather station, which is capable of detecting lightning up to 40 km away with 1km accuracy. While it’s not quite new technology, I found the Flash Bee design to be rather cute and convenient, and it looks really easy to reproduce. Flash Bee key components: Seeed Studio XIAO ESP32-C3 with Wi-Fi 4 & Bluetooth LE 5.0 connectivity ($4.90) Round Display for XIAO – 1.28-inch touchscreen display with 240×240 resolution, 65K colors, 100 Hz refresh rate ($18) Grove Lightning Sensor AS3935 ($26.90, alternative link if out of stock) 3.7V 400mAh LiPo battery Slide switch 2x M2 5mm […]

LR2021 LoRa Plus board combines Semtech LR2021 and Nordic nRF54L15 for high-speed FLRC and LoRa connectivity

Last year, Semtech released the LR2021 LoRa Plus transceiver chip, designed to address the low data-rate issue associated with LoRa, but surprisingly, they didn’t release a development board for the chip. Now, almost a year later, Seeed Studio and Semtech have partnered to introduce the LR2021 LoRa Plus development kit targeting long-range high-speed LoRa and FLRC applications up to 2.6 Mbps. Not only does the board support LoRa Gen 4 technology, providing Sub-GHz, 2.4 GHz ISM, and S/L-band operation, but a XIAO nRF54L15 board also adds dual-core processing (Arm Cortex-M33 + RISC-V) and supports other short-range protocols, including NFC, Bluetooth LE 6.0, Matter, Thread, and 2.4 GHz proprietary protocols. The development board also features a 0.96-inch 128×64 OLED, three Grove connectors for expansion, a USB Type-C for power, SWD debugging, and two Sub-GHz and 2.4 GHz SMA connectors. It is compatible with Arduino Uno, STM32 Nucleo, and Nordic DK boards. […]
