Boardoza TPAFE0808 8-Channel Configurable ADC/DAC/GPIO Breakout Board
The Boardoza TPAFE0808 is an eight-channel analog and digital interface board built around the 3PEAK TPAFE0808-LFPR-S. It expands a microcontroller’s signal-handling capabilities by providing software-configurable ADC inputs, DAC outputs, and general-purpose digital I/O through a single I²C interface. Each channel can be assigned independently, allowing analog measurements, voltage outputs, and digital signals to share the same board according to the application’s requirements. 3PEAK product information
An onboard REF3025AIDBZR supplies the nominal 2.5 V conversion reference, while separate VDD and VLOGIC connections provide access to the device supply and digital-interface supply. The board also includes interface pull-ups, hardware reset access, and solder-selectable addressing. These functions support applications such as reading analog sensors, generating programmable voltage setpoints, and adding configurable I/O to monitoring and control systems.
