About the Aegis mtstdp PCB

Aegis mtstdp is an open source PCB design by krishharma, published on GitHub under the MIT license. It is a 2-layer board measuring 80 × 50 mm, with 18 components from 14 distinct parts.

Other key parts include the AP2112K-3.3TRG1 and INA219AIDR. By type, the board carries 5 resistors, 4 connectors, 4 capacitors, 3 diodes and 2 ICs.

It belongs with the power & battery and sensors designs in this gallery.

From the project

Integer STDP continual-learning core for FPGA (Python golden model + Verilog). Tiny-net co-sim. IMU/power carrier PCB. Tables are simulator results. Not an ASIC.

Open aegisimucarrier.kicadpro. This is a 2-layer FPGA harness**, not an ASIC.

runkicad.py` upgrades the files for KiCad 10, runs ERC/DRC, fills GND zones, and writes Gerbers.

- J1 Digilent PMOD 2×6 → PYNQ-Z2 / Arty JA - Pin 1 UART (FPGA Y18) — not used by the IMU; leave as a probe - Pin 2 SCL (Y19) Pin 3 SDA (Y16) - Pin 5 / 11 GND - Pins 6 / 12 FPGA 3V3 unconnected so the onboard LDO and the FPGA 3V3 do not fight - J2 GY-521 (MPU-6050) 1×8: VCC GND SCL SDA XDA XCL AD0 INT. AD0 strapped to GND → I2C 0x68 - JUSB Micro-B + J4 5 V header, Schottky-ORed with J3 1S LiPo into VSYS - U1 AP2112K-3.3…
