MowerBoard
About the MowerBoard PCB
MowerBoard is an open source PCB design by pcailliatte, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 54 × 120 mm, with 101 components from 80 distinct parts.
Other key parts include the PTPS274C65ASRHAR, TPS62162DSGR, TPS7B8601QDDARQ1, MC33978AES and AVR128DB48X-X6LX. By type, the board carries 33 capacitors, 27 resistors, 21 diodes, 6 ICs, 4 connectors and 2 relays.
From the project
MowerBoard est une unité de contrôle électronique (ECU) alternative, robuste et 100% open-source pour tracteurs tondeuses autoportées thermiques.
MowerBoard est une unité de contrôle électronique (ECU) alternative, robuste et 100% open-source pour tracteurs tondeuses autoportées thermiques.
L'objectif principal de ce projet est de fournir une solution logicielle et matérielle entièrement libre. En mettant à disposition l'intégralité des schémas de conception, des fichiers de fabrication et du code source, nous démocratisons l'accès à une technologie généralement propriétaire et verrouillée par les fabricants.
