PCB projects

Fault-tolerant recovery avionics with triple-MCU voting and ten high-current deployment channels

A six-layer recovery controller built around two power trees, three independent STM32 domains, hardware voting, local sensing, and ten 24 V deployment channels. I owned the board end to end, from architecture and layout through bring-up and the full ten-channel deployment test.

Dual-band LR2021 flight telemetry system for 915 MHz / 2.4 GHz with switched diversity, RF-health telemetry, and hardware fault protection

The dual-band flight radio I am currently designing around one LR2021 and a CM5. It has separate 915 MHz and 2.4 GHz PA/LNA/filter chains, switched antenna diversity, forward/reflected-power sensing, twelve power-monitor channels, and hardware that can shut the RF side down without waiting on Linux.

~30 kW dual electric-pump power and control architecture with precharge, isolated power, sensing, and inverter CAN

The high-voltage electrical system I am designing for two electric propellant pumps. I own the overall architecture and the HV Control/inverter integration: precharge, main switching, isolated local power, pack/bus sensing, fault authority, and CAN to the two motor drives.

Redesign and validation of a 48 V flight engine controller for valve actuation, ignition, and sensor acquisition

A six-layer flight engine controller on the 48 V avionics bus. I inherited this board rather than designing it from scratch, and my revision work focused on the broken interfaces: BeagleBone pin mapping, connector/control/ADC-related routing, bring-up, integration, and validation.

Protected 12-cell battery interface and monitored power-distribution node for vehicle avionics

A four-layer battery-management and power-distribution board between the 12S pack and the Darcy avionics. I designed the schematic and PCB, ordered and assembled the hardware, then brought up the protected input, five switched outputs, and measurement paths.

Central flight-compute and black-box avionics board for sensing, storage, telemetry, and recovery coordination

The main compute and data-recording board in the flight stack. I helped review parts of the design, then owned the bring-up side: power characterization, processor/sensor/interface checks, debugging, and keeping the board usable through subsystem and vehicle integration.

Ground-to-vehicle magnetic pogo-pin interface for 48 V power, Ethernet, and safing across two launch vehicles

The magnetic breakaway umbilical I designed for both Vespula and Darcy/Felicette. A ground-side and vehicle-side PCB carry 48 V power, Ethernet, and safing/control through a compact pogo-pin interface that has to work electrically and also detach cleanly at launch.
