00:00Ground loops kill projects. Isolated power save boards from magic smoke.
00:05Looked everywhere, grabbed best hardware and deals for isolated converter builds every maker need.
00:11First up, KM003C USB-C tester. Cost $81.20. Monster tool handle PD 3.1 up to 240 watts.
00:23Capture ripple, sniff protocols, log power curves live.
00:26Price high, but stop you blowing expensive isolated DC supplies.
00:32Need clean input data, this deliver.
00:35Next, breakout adapter pack. Cost $2.89.
00:40Tiny surface mount isolated chips never fit breadboards.
00:44This give double-side PCB plates for SOI-Z, TSSOP, pitch down to .65mm.
00:50Pure bridge from SMD chip to test bench.
00:54Dirt cheap, save hours etching boards.
00:58Third, FT232RL USB to TTL board.
01:01Run 354.
01:03Built-in switch flick between 3.3 and 5-volt logic.
01:08Need talk to microcontrollers across isolation barrier without frying laptop USB port.
01:14Reliable chip, clean cereal, zero headache.
01:17Every bench need three in-drawer.
01:20Fourth, STM32G474VE dev board.
01:25Cost $9.50.
01:26ARM Cortex-M4 running 170 MHz, packed with math accelerators and high-res PWM timers.
01:34Perfect brain for driving custom isolated DC-DC switchers or closed-loop power stages.
01:40512K flash under $10 is steel.
01:43Fifth, 50-pack A03400 series MOSFETs.
01:48Just $320 for whole bag.
01:50SoT23-pack, pull over 5 amps, tiny gate charge.
01:55Perfect secondary side switches for low-voltage isolated power stages.
02:00Blow one during testing, cost pennies.
02:03Keep stash on bench always.
02:05Links for every tool and part sit down below.
02:09Smash like if build survived bench test.
