Customer Reviews

Based on 1 review
actualy, no software documentation provided

The product is well packaged, well documented about wiring. But there is no software documentation, and even if the base-component is the ADS1115, there is no running software sample describing how to configure the registers and how to read the voltage. Waiting for detailled information to use the product. Best regards. (Comment Robotshop: Thank you for your review. We have contacted you by email.)
