Description
A replacement control board made by ePIC Blockchain for Bitmain Antminers. It comes with ePIC's own PowerPlay firmware preinstalled and replaces the miner's original control board. The firmware supports overclocking, underclocking and undervolting, perpetual tuning, an API, and fleet management through the ePIC Dashboard. The board can run a miner with one to four fans or none, so fan simulators are not needed for immersion or inline-fan setups.
Compatibility
- Antminer S19 and S21 series (ePIC UMC V4.x)
- Tuning presets: S19j, S19j Pro, S19j Pro+, S19 XP, S19k Pro, S21, T21
Specifications
- Module: V4.3 System on Module
- Connectors: Ethernet, hashboard (J1 disabled by default), PSU, 4-pin fan and square fan
- MicroSD card slot and status LED
- Not included: microSD card, SD-to-USB adapter, power cords, Ethernet cable
Notes
- Connect the hashboards to J2, J3 and J4; J1 is disabled, and a hashboard plugged into it will not be detected.
- On an S19k Pro, plug the square fan connectors into FAN3 and FAN4 and the 4-pin fan connectors into FAN1 and FAN2.
- The board runs only ePIC firmware, and ePIC firmware runs only on the UMC board.
- The miner's original faceplate may not fit the UMC board.
