Raspberry Pi HAT with Dual-Channel RS485 Converter - Waveshare 17221

The KAmodRPi UART RS485 ISO is an advanced RS485 bus transceiver for the Raspberry Pi, featuring automatic transmission direction control, galvanic isolation, surge protection, and support for up to 128 modules at a transmission speed of up to 500 kbps, powered by 5V with low power consumption

The KAmod RPI 485&CAN Hat module extends the functionality of Raspberry Pi 5 boards (and others with a 3.3 V SPI interface) with two galvanically isolated RS485 interfaces and one CAN 2.0B interface. The RS485 interfaces are based on the SC16IS752 controller, and the CAN interface on the MCP2515 system. The isolated transceivers used (ADM2483 and TJA1052) increase resistance to interference. Communication takes place via two SPI interfaces, and additional power supply options (from RPi or external 8-32 V) and a stabilized 5 V output allow for flexibility in power supply. The module can be mounted on RPi 5, also with an Active Cooler radiator, and can work with other microcontrollers. The maximum transmission speeds are 500 kbps for RS485 and 1 Mbps for CAN

BTT U2C V2.1 is a versatile CAN Bus adapter, ideal for integration with Raspberry Pi. With ESD protection, a durable PCB surface, and support for firmware updates, it is a reliable solution for stable communication in 3D printing projects. BIGTREETECH U2C V2.1

PoE HAT (G) allows Raspberry Pi 5 to be powered without the need for an additional power cable, using only an Ethernet cable compatible with Power over Ethernet technology. With high output power and a compact design, the HAT is ideal for projects requiring stability, space efficiency, and clean integration—especially when used with the official Raspberry Pi 5 case.

KAmodRPi-GPRS-GPS is an overlay for Raspberry Pi 4 / 3B + / 3B / 2B / B + computers, which allows you to enrich the system with the ability to send data via GPRS, SMS transmission or work as a module for Bluetooth communication. This extension also offers the ability to receive satellite data from location systems - GPS and GLONASS.

The dual-channel PCIe adapter for Raspberry Pi 5 enables simultaneous use of two high-speed M.2 NVMe SSDs, significantly increasing the storage capacity and performance of Pi 5-based systems. The module supports booting from SSD and is ideal for data-intensive applications such as NAS, workstations, data logging systems, or server-based solutions.
