Key Selling Points Powerful Heart - 600MHz Cortex-M7 Dual Instruction Superscalar Architecture: Up to two instructions can be executed per clock cycle. In numerous integer and pointer operations, approximately 40%-50% of the time can be spent executing two instructions in parallel. Branch Prediction Technology: Branch prediction is introduced for the first time in an ARM microcontroller. Loop and conditional jump instructions require only one clock cycle, significantly improving code execution efficiency. Flexible Clock Management - Dynamic Frequency Adjustment, Uninterrupted Operation Supports dynamic clock adjustment. Unlike traditional microcontrollers, Teensy 4.0 does not affect the serial port baud rate or audio sampling rate when changing the clock frequency. Applicable Scenarios High-performance robot control Digital audio synthesis and processing (I2S, S/PDIF) High-speed data acquisition and real-time analysis Color: Green Material: PCB Package Contents: 1*Teensy 4.0 Development Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
