Communication with the AS7331 sensor is facilitated via I2C protocol, and the board conveniently provides access to the I2C bus pins through a Qwiic connector for easy, solderless assembly. Additionally, a through-hole header is available for those who prefer a more permanent, soldered connection, which also includes pins for the sensor's Interrupt and Sync functions. The sensor offers four selectable I2C addresses, which can be configured by adjusting the solder jumpers on the board.
To assist with rapid deployment, a dedicated Arduino library has been developed for the AS7331, simplifying the configuration process and data acquisition from the sensor. The SparkFun Qwiic Connect System, to which this sensor belongs, is a cohesive collection of I2C-compatible components that streamline prototyping and reduce the likelihood of connection errors.
Please note that the sensor requires an operating voltage between 2.7V and 3.6V and has three distinct power modes to accommodate various energy consumption needs. The sensor's high dynamic range and the presence of two Qwiic connectors underscore its versatility and ease of integration into a wide array of projects.
If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product. (‘’RA’’) numbers are valid for 30 days, within which time the returned Products should be received by the Vendor. No returns will be accepted without having previously obtained an (‘’RA’’) number. The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
