In the realm of electronics and circuit board design, innovation and precision are paramount. Among the myriad of developments in this field, the C3E-MB-PCB-V4 stands out as a notable advancement. This article aims to provide an in-depth look at the C3E-MB-PCB-V4, exploring its features, applications, and the impact it has on the industry.
The C3E-MB-PCB-V4 brings several improvements over previous versions (V2/V3):
Better compatibility with newer automotive CAN-BUS systems.
: Physical buttons for BOOT (GPIO9) and RESET (EN) to manually enter download mode for firmware flashing.
: Powered by the ESP32-C3 , featuring integrated Wi-Fi and Bluetooth LE 5.0.
: Typically features 400 KB of internal SRAM and is often paired with 4 MB of on-board SPI flash in standard module configurations like the ESP32-C3-WROOM-02 . Technical Design (V4 Iterations) c3e-mb-pcb-v4
The main oscillator (25MHz, ±30ppm) is located near the compute module edge. Using an oscilloscope (500MHz minimum), probe TP12 (CLK_OUT). On V4, the signal should show less than 150ps of jitter. Higher jitter indicates shielding failure near the crystal.
The design files for have been finalized and pushed to the repo. Please review the Gerber files before we send the order to the fab house.
