Generate a perfectly fitted, 3D-printable case for your PJRC Teensy 4.0. Verified 35.56x17.78mm base dimensions with Above-board for pin headers; below-board for solder + SDIO card if used.
Teensy 4.0 dissipates 200-400mW — passive cooling handles typical workloads.
Teensy targets DSP, audio, and performance-critical embedded work. PETG is default. ABS extends thermal headroom for sustained DSP workloads. PC for industrial or automotive DSP deployments.
Micro-USB is the ONLY programming path — no bootloader button; programming happens via Teensy Loader over USB.
MicroSD slot (Teensy 4.1) on underside — reserve below-board access if using.
Ethernet magjack (Teensy 4.1) — tall port (~14mm above board); add clearance.
Audio Adaptor board stacks under Teensy — provide below-board clearance if used.
Teensy has NO wireless — no antenna keepout.
Do NOT apply pressure to the top surface — bare MCU is underneath with no shield can.
