Read the mining signals
Hashrate, shares, best difficulty, pool state, block height, and uptime are presented for each device.
An ESP32 solo-lottery mining family
Three compact ESP32 editions. Device-specific displays. A local dashboard served by the miner itself.

Three device editions
The same mining family, tailored to a color touchscreen, a tiny OLED, or a headless board.
| Hardware | Display & form factor | Hashrate class |
|---|---|---|
| ESP32-2432S028R | 2.8-inch color touchscreen | ~750 kH/s |
| ESP32-C3 OLED | 0.42-inch compact OLED | ~300 kH/s |
| ESP32-C3 Super Mini | Headless compact edition | ~300 kH/s |
Approximate hardware classes, not performance guarantees. Every edition provides a local network dashboard.
The device experience
Setup, on-device status, local monitoring, and hardware-specific controls are developed as one coherent family.
The color edition offers the richest display experience. OLED keeps the essentials in a pocket-size display. Super Mini removes the screen for a tiny headless miner.
Each edition serves its dashboard on the local network. Monitoring does not require a JBR Miner cloud account.


Hardware that explains itself
Hashrate, shares, best difficulty, pool state, block height, and uptime are presented for each device.
Status and supported configuration remain accessible without a separate app or cloud account.
Color, OLED, and headless editions retain controls appropriate to the actual board, with ongoing firmware and stability work.
Solo lottery
JBR Miner is a hobbyist Bitcoin solo-lottery device. Compact hardware contributes hashing work toward a solo-mining pool.
It is not a promise of profit or a shortcut around Bitcoin's network difficulty.
Three working editions remain under active refinement. Device guidance, support information, and release documentation will expand as they are ready.
