Product Description

TDS Workshop is one of the development tools provided by Holtek. It is convenient for users to develop TDS related products and shorten the development cycle. The TDS platform integrates the rich functions of TDS measurement, temperature measurement, key, display, communication etc. It can quickly configure and generate target code. The TDS platform also provides a calibration monitoring window to calibrate the monitoring data conveniently, and provides four platform examples for users to reference design or use directly.

ESK-TDS-66F0176 is the TDS Development Board – TDS Module (HT66F0176) (sub-board).
The development board can be connected to the TDS Display Board (motherboard) to verify and test with the TDS Workshop software, and to help users develop TDS related products quickly, which greatly improves the development efficiency and reduces the development cost.
