It plugs directly onto the Pico via the onboard female pin header — no wiring required.\n\nThe module provides two independent RS232 channels with TVS and ESD diode protection. UART status LEDs indicate RX/TX activity on each channel, and a DB9 male connector can be used via an adapter cable. Demo code is available for both C/C++ and MicroPython.\n\nKey Features\n\n\n2 RS232 Channels – Independent UART-to-RS232 conversion on each channel\n\nSP3232EEN Transceiver – Reliable RS232 level conversion\n\nDirect Pico Attachment – Female pin header for plug-and-play connection\n\nTVS & ESD Protection – Onboard diodes protect against surges and static discharge\n\nUART Status LEDs – RXD/TXD indicators for each channel\n\nDB9 Compatible – DB9 male connector available via adapter cable\n\nDemo Code Included – C/C++ and MicroPython examples for Raspberry Pi Pico\n\n\nSpecifications\n\n\nRS232 Transceiver: SP3232EEN\n\nCommunication Bus: UART\n\nOperating Voltage: 3.3V–5V\n\nBaud Rate: 300–912,600 bps\n\nChannels: 2\n\n\nIdeal For\n\nConnecting Raspberry Pi Pico to RS232 industrial devices\nSerial communication with legacy equipment\nUART-to-RS232 bridging projects\nData logging from RS232 sensors\n\n\nPackage Contents\n\n1× 2-Channel RS232 Module for Raspberry Pi Pico\n\n\n\nNote: Raspberry Pi Pico is not included.\n\n\nResources\n\nWaveshare Wiki – Pico-2CH-RS232\n","vendor":"Waveshare","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":14634,"title":"Default Title","sku":"WS-19979","price":9.8,"on_sale":false,"in_stock":true,"available_quantity":18,"option1":"Default Title"}]}
