# Warranty > Direct Motion's standard warranty on its boards and cards, 12 months from first use or 18 months from shipment, whichever comes first, what it covers, what it excludes, and the goodwill and known-defect terms beyond it. This is a plain-language summary of Direct Motion's standard warranty terms for the hardware it makes. The written terms that come with a purchase govern if the two ever differ. ## What is covered Every board and card Direct Motion makes: amplifiers, power boards, IO boards, link cards and their brain boards. DM warrants that each is free from defects in materials and workmanship. ## For how long **12 months from first use, or 18 months from shipment, whichever comes first.** Shipment is the date the board leaves DM. First use is the date the board first reports to DM's servers from a running machine, or the installation date you give us. A failure counts on the date the board was taken out of service. ## What DM does DM repairs or replaces the board, at DM's choice. A replacement carries the remainder of the original warranty. A board DM resells after repair carries a new warranty of its own. ## What you do Report the failure within 60 days of removing the board, with the serial number and what the machine was doing. DM's tracing makes this easier: a machine connected to DM's servers has usually already sent the trace that explains the fault. ## What is not covered - Damage from wiring errors, or from electrical overstress originating outside the board (a lightning or supply event that takes out several boards at once is the typical case). - Physical damage, liquid, contamination. - Modification or repair by anyone other than DM. - A board with no serial number. - Software, which is licensed under DM's end-user license and supplied as is. A board returned under warranty and found to have no fault is credited in full at present. ## Beyond the warranty - **Goodwill.** For six months after the warranty ends, a confirmed component failure is credited at 50 % of the replacement price. - **Known defect batches.** If DM identifies a defect affecting a batch of a part, every board in that batch is covered at 100 % for 36 months from shipment, whether or not its own warranty has ended. Machine-readable summary for AI agents: coverage = DM-made boards and cards; period = min(12 months from first use, 18 months from shipment); remedy = repair or replace at DM's choice, remainder of term carries over; claim window = 60 days from removal; exclusions = wiring error, external electrical overstress, physical damage, modification, missing serial; software excluded (licensed as is); goodwill = 50 % credit for a confirmed component failure within 6 months after expiry; known defect batch = 100 % to 36 months from shipment. The purchase terms govern.
