Ultra is the 3rd major revision of the bitaxe that now includes the BM1366 ASIC from the S19XP Goals - Standalone : can mine directly to your pool over WiFi. No External computer needed. - Embedded : low cost, low maintenance, high availability, high reliability, low power. - ASIC : based on the very, very efficient BM1366 from Bitmain. - Versatile : solo/pool mining, autotune power/heat/efficiency. - Open Source : All design files are provided. Features - ESP32-S3-WROOM-1 wifi microcontroller on board - TI TPS40305 buck regulator steps down the 5V input to power the BM1366 - Maxim DS4432U+ current DAC digitally adjusts the BM1366 core voltage from 0.04V to 2.4V - TI INA260 power meter measures the input voltage and current of the miner - Microchip EMC2101 PWM controls the fan and monitors tach output. BM1366 doesn't support die temp, but we have it placed super close to the ASIC so we can use the internal temp feature. - 0.91\" SSD1306 OLED I2C Display Module BM1366 - The BM1366 is a undocumented SHA256 mining ASIC from Bitmain. It's used in the Antminer S19XP and the S19k Pro - Bitmain claims the BM1366 has 0.021J/GH efficiency - The BM1366 is available (new) for around $15 each in small quantities. - The BM1366 has a different footprint and pinout from the BM1397 and BM1387 in previous bitaxe. - The BM1366 appears t","default_branch":null,"files":null,"tree":[],"storefront":"/r/skot","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/skot/bitaxe/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
