You\nwould be, if you didn't have this ultra-cool CJMCU-9548 1-to-8 I2C\nmultiplexer! Finally, a way to get up to 8 same-address I2C devices hooked up\nto one microcontroller - this multiplexer acts as a gatekeeper, shuttling the\ncommands to the selected set of I2C pins with your command.Using it is fairly\nstraight-forward: the multiplexer itself is on I2C address 0x70 (but can be\nadjusted from 0x70 to 0x77) and you simply write a single byte with the\ndesired multiplexed output number to that port, and bam - any future I2C\npackets will get sent to that port. In theory, you could have 8 of these\nmultiplexers on each of 0x70-0x77 addresses in order to control 64 of the\nsame-I2C-addressed-part.Like all breakouts, we put this nice chip on a\nbreakout for you so you can use it on a breadboard with capacitors, and\npullups and pulldowns to make usage a snap. Some header is required and once\nsoldered in you can plug it into a solderless-breadboard. The chip itself is\n3V and 5V compliant so you can use it with any logic level.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eInterface: I2C IIC\u003c\/li\u003e\n \u003cli\u003eChip: TCA9548A\u003c\/li\u003e\n \u003cli\u003eSelectable I2C address: 0x70-0x77\u003c\/li\u003e\n \u003cli\u003eWorking Voltage: 1.65-5.5V\u003c\/li\u003e\n \u003cli\u003eMax Clock Frequency: 400KHz\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2024-07-17T00:50:23+10:00","created_at":"2024-07-17T00:50:23+10:00","vendor":"DEVMO","type":"Video Multiplexers \u0026 Quads","tags":["electronics_July2024_update"],"price":8700,"price_min":8700,"price_max":8700,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":44604022554777,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B07T3B1F5B","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"CJMCU-9548 TCA9548A 1-to-8 I2C 8-Way Multi-Channel Expansion Multiplexer Breakout Board IIC Mod P0I7","public_title":null,"options":["Default Title"],"price":8700,"weight":9,"compare_at_price":null,"inventory_management":"shopify","barcode":"796753378335","requires_selling_plan":false,"selling_plan_allocations":[]}],"images":["\/\/soundstores.net\/cdn\/shop\/files\/B07T3B1F5B.jpg?v=1721142636","\/\/soundstores.net\/cdn\/shop\/files\/61RKRA_sRlL.jpg?v=1721141428","\/\/soundstores.net\/cdn\/shop\/files\/612-0JZEAzL.jpg?v=1721141428"],"featured_image":"\/\/soundstores.net\/cdn\/shop\/files\/B07T3B1F5B.jpg?v=1721142636","options":["Title"],"media":[{"alt":null,"id":31428619108505,"position":1,"preview_image":{"aspect_ratio":1.0,"height":1600,"width":1600,"src":"\/\/soundstores.net\/cdn\/shop\/files\/B07T3B1F5B.jpg?v=1721142636"},"aspect_ratio":1.0,"height":1600,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/B07T3B1F5B.jpg?v=1721142636","width":1600},{"alt":null,"id":31428496457881,"position":2,"preview_image":{"aspect_ratio":1.0,"height":1600,"width":1600,"src":"\/\/soundstores.net\/cdn\/shop\/files\/61RKRA_sRlL.jpg?v=1721141428"},"aspect_ratio":1.0,"height":1600,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/61RKRA_sRlL.jpg?v=1721141428","width":1600},{"alt":null,"id":31428496490649,"position":3,"preview_image":{"aspect_ratio":1.0,"height":1600,"width":1600,"src":"\/\/soundstores.net\/cdn\/shop\/files\/612-0JZEAzL.jpg?v=1721141428"},"aspect_ratio":1.0,"height":1600,"media_type":"image","src":"\/\/soundstores.net\/cdn\/shop\/files\/612-0JZEAzL.jpg?v=1721141428","width":1600}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eCJMCU-9548 TCA9548A 1-to-8 I2C 8-Way Multi-Channel Expansion Multiplexer Breakout Board IIC Mod P0I7\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eDESCRIPTION You just found the perfect I2C sensor, and you want to wire up two\nor three or more of them to your when you realize \"Uh oh, this chip has a\nfixed I2C address, and from what I know about I2C, you cannot have two devices\nwith the same address on the same SDA\/SCL pins!\" Are you out of luck?
