16x 3-pin servo headers along Y=0 edge need top+front cable room; V+ terminal block at top center
addr jumpers A0-A5 (0x40-0x7F); chainable; 25mA/channel logic - servo current via V+ rail
HiLetgo clone assumed dimensionally identical to Adafruit 815 (standard clone layout) - spot-check hole pattern with calipers if fit-critical
