Proto.supply exists because we were tired of buying electronic components from stores that couldn't tell us if something was actually in stock, what voltage it ran at, or when it would arrive.
To build the electronics store we always wanted — one where every spec is verified, every stock count is real, and every order ships with a proper GST invoice.
We're engineers building for engineers. No stock photos of components we don't have. No "ships in 7-14 days" guessing games. Just honest, data-first commerce.
Verified Specs
We cross-check every datasheet. Voltage, pinout, dimensions — all confirmed.
