SPIDER Automation Wemos TTGO Xi 8F328P-U Development Board | USB Programmable 8F328 Series MCU | ADC, DAC & PWM
Description
The Wemos TTGO Xi 8F328P-U is a compact microcontroller development board designed for embedded-system development, firmware programming and electronics prototyping. An integrated USB interface allows the board to connect directly to a computer for programming, eliminating the need for a separate USB programming interface for normal development use.
The board operates from 3.3V to 5V and supports a clock frequency of 16MHz. Its integrated high-precision RC oscillator eliminates the requirement for an external crystal oscillator, while the simplified circuit architecture uses fewer peripheral components and helps keep the board compact.
For analog and control applications, the board provides a 12-bit ADC, DAC functionality and 8 PWM channels. It also incorporates calibrated internal reference-voltage sources at 1.024V, 2.048V and 4.096V with ±1% accuracy, providing useful reference options for precision-oriented analog measurement and control applications.
The MCU also provides a unique device identifier that can be used for chip identification, device-specific software functions and application-level program encryption or security implementations. The board can be developed using the Arduino IDE after installing the appropriate LGT support package.
