PROFILE
Jackie
Jackie Lee contributed to the ISS-PCB repository over four months, focusing on hardware design and PCB development using KiCad and schematic capture tools. Jackie delivered four hardware features, including integrating an ADC expander, adding pull-up resistors for I2C reliability, and supporting a second stepper driver for Motor-MK1 to enable higher torque. Their work included schematic updates for power management, signal integrity, and grounding improvements, such as correcting ESP32 3V3 grounding. All changes were hardware-focused, with clear commit traceability and readiness for validation. Jackie’s approach emphasized robust hardware integration, manufacturability, and risk reduction through careful schematic and PCB design.

Nov 1, 2024In 2024-11, ISS-PCB delivered a MIDAS-MK2-Pyro hardware design update, improving power management and signal integrity. The schematic was updated to connect DRDY to a GPIO expander and to add dedicated power isolation components, enhancing interaction between DRDY-driven peripherals and power rails. These changes strengthen power integrity and reduce cross-talk, enabling more robust pyro sensing/control workflows. The update is tracked via a single commit for traceability: 251522147bdc363a7fd450da5421f8d350d4fc31.
