RJ45 Ethernet Development Board (ESP32-S3) Option:ESP32-S3 Board Only Field tests with conventional dual-channel

Field tests with conventional dual-channel AIS receivers showed

along with two 2×1-pin male headers and shorting blocks for the buzzer and battery-level jumpers

just use the DSI cable and power the Raspberry Pi and Display separately (the display will require at least 5V 1A via the USB-C port)

it’s accurate and feature-rich enough to serve as a primary multimeter

RJ45 Ethernet Development Board (ESP32-S3) Option:ESP32-S3 Board Only Field tests with conventional dual-channelThis ETH board is a development platform built around the ESP32 S3R8 chip, with both wireless and wired connectivity options. It supports 2. 4GHz Wi Fi, and Bluetooth 5 (LE) and includes an RJ45 Ethernet port for wireless communication, while the W5500 Ethernet chip provides 10 100Mbps wired network capabilities via the SPI interface. An optional PoE module is available, making it ideal for projects that require power over Ethernet. It includes a
