4.3-inch ESP32-S3 wireless touchscreen display features terminal block with RS485, CAN Bus, I2C, DIO

ESP32-S3 display RS485 CAN Bus terminal block

Waveshare “ESP32-S3-Touch-LCD-4.3B” is a capacitive touch display development board built around an ESP32-S3 SoC with RS485, CAN Bus, I2C, and isolated DIO interfaces provided through a terminal block. The devkit features a 4.3-inch capacitive touch display that has an 800×480 resolution, RTC, and a microSD card slot. Combined with a wide input voltage range of 7-36V DC, the ESP32-S3-Touch-LCD-4.3V is suitable for IoT HMI, smart home automation, and more. Previously we have written about similar development boards from Waveshare like the ESP32-S3 1.69-inch touch display, the $15 Waveshare 1.69-inch IPS touch LCD module, the Waveshare RP2040-LCD-0.99-B rounded display but they would offer no expansion pins or GPIO through pads or 4-pin connectors, while the ESP32-S3 display features a terminal block with additional interfaces like RS485 pr CAN Bus that should make wiring more convenient and versatile for the target applications.

Serial Bus Servo Driver HAT (A) can drive up to 253 servos simultaneously

Waveshare Bus Servo Driver HAT (A)

Waveshare has recently introduced the Serial Bus Servo Driver HAT (A) ESP32-powered servo motor controller for the Raspberry Pi designed to drive up to 253 serial servos simultaneously. The servos can be controlled via UART or USB through the Pi SBC or used as a standalone controller for a robotics project. The board has a wide input voltage range of 9 to 25 volts and features an onboard XT60 connector, a screw terminal, and a DC barrel jack any of which can be used as power input. Besides that, the board features an RS485 port a TTL Servo header, and a UART control switch for convenience.

Dusun DSGW-130 smart home controller fits into an 86-type junction box

DSGW 130 Zigbee Touch Screen Control Panel

The Dusun DSGW-130 smart home controller is a Rockchip PX30-powered, touch-enabled control panel designed to fit into an 86-type junction box. It runs on Android 11 and can connect to your home network using Wi-Fi and Zigbee, similar to the SONOFF NSPanel Pro. The only glaring difference I can see from the specifications is that the DSGW-130 has a few extra features like more storage, a wired network connection, RS485, and support for newer 5GHz Wi-Fi, which the SONOFF doesn’t have. We’ve also written about other similar controllers, like the SONOFF NSPanel, and reviewed the SONOFF NSPanel Pro with Zigbee and the CAM Slim WiFi camera. Check them out if you’re interested in similar products.
