Two-digit 7-segment thru-hole displays package two numeric fields in one molded body, with shared segment pins and independent digit strobe pins — halving connector count versus two single-digit parts. QUEENDOM 2-digit modules serve scoreboards, temperature controllers, batch counters, and time displays in red, green, amber, and blue with 10 mm to 25 mm digit heights.Common-anode and common-cathode variants cover both direct-drive and multiplexed designs; multiplexing at 200+ Hz per digit avoids flicker while keeping firmware duty-cycle simple. Displays are intensity-binned at 10/20 mA test current for uniform brightness. Wave-solderable leads follow standard 2.54 mm pitch.
