Built around the \u003cstrong\u003eRT8537\u003c\/strong\u003e controller (green PCB version), it accepts a \u003cstrong\u003e2V–24V input\u003c\/strong\u003e and delivers an adjustable \u003cstrong\u003e5V–28V output\u003c\/strong\u003e at up to \u003cstrong\u003e2A\u003c\/strong\u003e with over \u003cstrong\u003e93 % efficiency\u003c\/strong\u003e. The module installs directly without wire jumping or soldering modifications, restoring power to the hashboard's voltage rail in minutes.\u003c\/p\u003e\n\u003ch3\u003eWhen the Hashboard Voltage Rail Fails\u003c\/h3\u003e\n\u003cp\u003eThe L3+ and S9 hashboards use on-board buck\/boost converters to generate the regulated voltages that feed each ASIC chip group. When one of these converters fails, the entire voltage domain it supplies goes offline — the affected chips stop hashing and the board reports partial or zero hash rate. Replacing the failed on-board converter with a discrete boost module bypasses the faulty circuit and restores the correct voltage without reflowing the original components.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003ePower off the miner and remove the hashboard. Identify the failed voltage domain by checking which chips are offline in the miner log. Solder the module's input pads to the board's supply rail and the output pads to the regulated rail downstream of the failed converter. Adjust the trimmer potentiometer to set the output to 14V using a multimeter. Reinstall the hashboard and verify that the previously missing chips now appear in the hash chain with normal operating voltage.\u003c\/p\u003e\n\u003ch4\u003e14V Boost Module Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eController IC\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eRT8537\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eInput Voltage\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e2V – 24V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e5V – 28V (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eMax Output Current\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e2A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eEfficiency\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e\u0026gt;93 %\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eProtections\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eUVLO, thermal shutdown, current limiting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eDimensions\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e36 × 17 × 14 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAntminer L3+, S9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated L3+ \/ S9 Hashboard Voltage Modules\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mt3608-mt3608b-boost-module-24v-hashboard-antminer-l3-s9-blue\"\u003eMT3608 Boost Module 24V – Antminer L3+ \/ S9 Hashboard (Blue)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/xl6009-dc-voltage-regulator-s17-s17pro-t17e-hashboard-buck-boost-converter-module\"\u003eXL6009 Buck-Boost Converter Module – Hashboard Voltage Regulator\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antminer-l3-220-inductor-voltage-booster-hashboard-repair\"\u003eAntminer L3+ 220 Inductor Voltage Booster – Hashboard Repair\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/antminer-l3-u73-step-down-power-module-dc-board-voltage-regulator-black-version\"\u003eAntminer L3+ U73 Step-Down Power Module – Black Version\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRepairing L3+ or S9 hashboards in volume? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for bulk pricing on boost modules and hashboard components.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":41715613008051,"sku":null,"price":1.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/L3-S9-Boost-module-14V-Hash-board-6R8-RT8537-Green-version-Voltage-regulator.webp?v=1747701999","url":"https:\/\/lys-sz.com\/products\/l3-s9-boost-module-14v-hashboard-rt8537","provider":"LYS Shenzhen","version":"1.0","type":"link"}
