PCB Business Card
About the PCB Business Card
PCB Business Card is an open source PCB design by AmirAlsad, published on GitHub under the MIT license. It is a 2-layer board measuring 88.9 × 50.8 mm, with 6 components from 6 distinct parts.
Other key parts include the NT3H2111W0FHKH. By type, the board carries 2 capacitors, 1 IC, 1 antenna, 1 diode and 1 resistor.
From the project
NFC + silkscreen PCB cards designed for MIT Beta Theta Pi rush week 2025 — KiCad sources, vendored library, and as-manufactured gerbers.
A brother taps this card to a phone; the phone opens the chapter's rush link. No battery, no app on the brother's side — the card is a passive NFC tag that harvests power from the reader's field.
This is the version that was manufactured and used during rush week 2025. The earlier iteration in ../brother-card-v1/ was never built.
A phone's NFC reader radiates a 13.56 MHz field. The spiral coil on the left half of the card (ANT1) is an inductor tuned, together with the IC's internal 50 pF and the tuning cap C2, to resonate at that frequency. At resonance the coil couples strongly to the…
