It lead out all the useful pins except the 3 ports required for RS485. In addition, it also has a wide voltage step-down circuit and can be powered by DC 7-30V. When plugged into the ESP32 board, it becomes a cost-effective main control board with WIFI and RS485.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif;\"\u003e\u003cspan style=\"font-size: 18px;\"\u003e38PIN ESP32(ESP32 DevkitC v4) RS485 Expansion board\u003cbr\u003e1 Working voltage DC 7-30V, input reverse polarity protection.\u003cbr\u003e2 With DC 5V external output power supply, minimum output current 0.5A, output short circuit protection.\u003cbr\u003e3 DC 3.3V\/100MA outputpower supply(output only after inserting ESP32 board)\u003cbr\u003e4 Lead out almost all IO ports (Except RS485 PIN IO1\/IO3\/IO17)\u003cbr\u003e5 With high-speed RS485 interface (Baud Rate 0.05K-1000KBPS)\u003cbr\u003e6 RS485 interface with surge protection\u003cbr\u003e7 Optional industrial standard DIN rail enclosure\u003cbr\u003e8 Terminal spacing: 3.96mm.\u003cbr\u003e9 Terminal Blocks: Wire Range 26-16AWG, Strip Length 3.96mm, Metric M2\/M2.5 Slotted Screws.\u003cbr\u003e10 Size: 72 *58 * 12mm(only Board),88 *61 * 35(with Rail Box)\u003cbr\u003e11 Weight: 38g(only Board),90g(with Rail Box)\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif;\"\u003e\u003cspan style=\"font-size: 18px;\"\u003e\u003cspan style=\"color: rgb(0, 0, 205);\"\u003eUse:\u003cbr\u003eDIN Rail Mount Screw Terminal Adapter Module for 38 PIN ESP32 Board(ESP32 DevkitC v4).\u003cbr\u003eWith this adapter modules, you can easily extend your ESP32 projects to industrial control applications.\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif;\"\u003e\u003cspan style=\"font-size: 18px;\"\u003e\u003cspan style=\"color: rgb(255, 0, 0);\"\u003eNotice:\u003cbr\u003e1:This is just an expansion board.
