Waveshare 8-channel RS485 to Ethernet industrial serial servers work as a Modbus & MQTT gateways, RS485-to-JSON converters

Industrial Isolated 8 Ch RS485 to RJ45 Ethernet Serial Server

Waveshare has launched the 8-Channel RS485 TO ETH (B) and 8-Channel RS485 TO POE ETH (B) industrial Ethernet serial servers designed for bi-directional transparent data transmission between RS485 and Ethernet networks. The only difference is PoE support, one has it, the other doesn’t, recognizable by their names. It features eight RS485 channels that operate independently, and supports two Ethernet ports (with an optional PoE version compliant with IEEE 802.3af). Key features include working as a serial server, Modbus gateway, MQTT gateway, and RS-485 to JSON converter. It also supports protocols like TCP, UDP, HTTP, DHCP, DNS, and more. It works in the industrial temperature range (-40°C to 85°C), offers power and signal isolation, 2kV surge protection, and comes housed in a durable aluminum alloy enclosure. Additionally, it supports wall-mount or rail-mount installation, multiple power supply methods (DC 7–36V via screw terminal or PoE), and web browser/device library configuration. These features make […]

Raspberry Pi Pico-sized RP2350 CAN development board features a clone of the MCP2515 CAN Bus controller

Waveshare has recently launched RP2350-CAN, a Raspberry Pi RP2350-powered CAN development board with onboard XL2515 CAN Bus controller and a SIT65HVD230 CAN transceiver. The board supports the CAN V2.0B protocol at up to 1 Mbps, and the XL2515 chip appears to be a clone of the popular Microchip MCP2515 CAN controller. The board includes the same 26 multi-function GPIO pins and USB-C port as found on the Raspberry Pi Pico 2. Other features include a DC-DC buck-boost converter (MP28164), BOOT and RESET buttons, a user LED, a selectable 120Ω CAN termination resistor, and CAN screw terminals. The CAN Bus board targets automotive, industrial control, and robotics applications. Waveshare RP2350 CAN specifications: SoC – Raspberry Pi RP2350A CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot OR Dual-core RISC-V Hazard3 @ 150 MHz Up to two cores can be used in any combination Memory – 520 KB on-chip SRAM […]

Batteryless 7.5-inch NFC-powered e-paper display V2 gets new NFC chip and “fast flashing method”

7.5inch NFC Powered e Paper V2 side view

Back in 2020, we wrote about Waveshare’s Batteryless NFC e-paper display, which can work without a battery and draws power and data from an NFC-enabled smartphone or the company’s ST25R3911B NFC board. Waveshare has now released a V2 version of this display with a new and improved NFC chip, a “fast flashing method”, and enhanced contrast. The new batteryless, 7.5-inch NFC-powered e-paper display features an 800×480 resolution and updates via an NFC-enabled smartphone or reader. It offers a 170° viewing angle and comes in a durable ABS plastic shell. The ST25R3911B NFC board allows updates via USB, SD card, or serial port, with an optional password lock. However, precise NFC positioning is required for updates. These features make it ideal for shelf labels, equipment tags, and other applications.
