Development Tools
Electronics development tools and DIY parts for prototyping and firmware bring-up: flash programmers (CH341A, XGecu T48), breadboards, OLED displays, touch sensors, relay boards, 3.3 V regulator modules, and micro servos. Prices are in line with mainstream electronics sellers, and small parts ship at USD 4.99, free from USD 39 when the order has only small parts.Pick parts by supply voltage first: most modules here take 3.3–5 V logic, while servos and relay coils want their own 5 V supply. Custom carrier boards, programming fixtures, and bring-up tooling are available by quote.
