The Things Indoor Gateway Pro: A Managed LoRaWAN Solution with ESP32 and Semtech SX1302
The Things Industries first introduced the Things Indoor Gateway, an affordable multi-channel LoRaWAN gateway designed for IoT networks in 2019. While low-cost single-channel gateways like Dragino OLG01, priced as low as $83.50, were available, they often struggled with connectivity in shared environments. The Things Indoor Gateway, priced around $111, offered a reliable solution for large-scale IoT deployments. Building on this success, the company has now launched the next-generation Things Indoor Gateway Pro. This managed LoRaWAN gateway is designed for seamless IoT network installation, featuring zero-touch provisioning, full cloud management, and flexible connectivity options including LTE, Ethernet, and Wi-Fi with automated failover. With advanced device management tools such as mTLS, FOTA, and secure boot, the Things Indoor Gateway Pro is a future-ready solution tailored for evolving IoT needs. Previously, we explored a variety of LoRaWAN gateways, including the AgroSense LoRaWAN for high-precision agriculture, the WisGate Soho Pro RAK7267 for greenhouse monitoring, […]
ESP32-C6 WiFi 6 and Bluetooth 5.0 USB-C development board integrates 1.47-inch TFT LCD Display
Waveshare has introduced the ESP32-C6-LCD-1.47 development board powered by an ESP32-C6 RISC-V microcontroller with WiFi 6 and Bluetooth 5 connectivity and equipped with a 1.47-inch display with a 172×320 resolution. With a 4MB flash, an RGB LED, and a microSD card slot for extra storage, this board is suitable for projects that need a compact display, low power consumption, and wireless connectivity such as AIoT applications and human-machine interfaces (HMI). Earlier this month, we covered the ESP32-S3 USB dongle, another development board from Waveshare designed for HMI applications with the same 1.47-inch display with a 172×320 resolution, but a USB Type-A port instead of the USB-C port found in the model covered today. In the past, we’ve written about other ESP32-based development boards for HMI applications, including the LILYGO T-HMI, ESP32-S3-Touch-LCD-4.3B, and Waveshare’s ESP32-S3 LCD Driver Board supporting both square and round displays. Feel free to check them out if […]
M5Stack ESP32-S3-Pico-based devkits: ATOMS3R with 0.85-inch color display, and ATOMS3R Cam with VGA camera
M5Stack ATOMS3R and ATOMS3R Cam are two tiny devkits based on ESP32-S3-Pico system-in-package and a similar design but the first one features a 0.85-inch color color IPS display, while the other is equipped with a GC0308 VGA camera. Both modules measure just 24x24mm with a thickness of around 13mm, integrate BMM150 and BMI270 motion sensors, offer GPIO expansion through female headers and a grove connector, and feature an infrared transmitter and a USB Type-C port for power and programming. Those are the second devkits based on the ESP32-S3-Pico SiP after we covered the tiny OMGS3 module earlier this week.

LiteWing DIY ESP32 drone costs about $12 to make
Circuit Digest’s LiteWing is a low-cost DIY drone controlled by an ESP32 module, based on a custom PCB and off-the-shelf parts that costs around 1000 Rupees to make, or $12 at today’s exchange rate. The DIY ESP32 drone was designed as a low-cost alternative to more expensive DIY drones that typically cost close to $70. The result is a WiFi drone that fits in the palm and controlled over WiFi using a smartphone. Interestingly it does not include any 3D printed parts as the PCB forms the chassis of the device. DIY ESP32 drone key features and components Wireless module – ESP32-WROOM-32 for WiFi control using a smartphone. Storage – MicroSD card slot Sensors – MPU6050 IMU for stability control.
