Kryvado Setup & Troubleshooting Guide
This guide walks you through assembly, Wi-Fi setup, mining configuration, and solutions to the most common issues users experience.
Step 1 — Assemble the Acrylic Case
• Remove protective film from all acrylic panels.
• Align the LCD screen with the front window panel.
• Use the screws + gold screw nuts on the back plate.
• Place the front acrylic panel and insert the screws into the corners.
• Tighten gently — acrylic can crack if overtightened.
Step 2 — Power On & Enter Wi-Fi Setup Mode
• Plug the device into any USB power source (5V / 1A minimum).
• After ~15 seconds, the device enters setup mode automatically.
• On your phone or computer, connect to Wi-Fi network:
SSID: nmap-2.4g (open network, no password)
• If no page opens automatically, open this in your browser:
http://192.168.4.1
Step 3 — Create a Bitcoin Address (Skip this step if you have a Bitcoin Address)
Kryvado needs a Bitcoin (BTC) receive address to direct mining rewards. If you already have a BTC address from a wallet or exchange, you can skip this step.
Quick steps (BitAddress.org):
1) Open BitAddress in a new tab.
2) Move your mouse around the page (or type random characters) until the progress reaches 100%.
3) The site will generate a Bitcoin Address and a Private Key.
4) Copy the Bitcoin Address (this is what you paste into your device in the next step).
5) Store your Private Key securely — do not share it with anyone.
Security warning: Your Private Key controls the funds for that address. If it’s leaked, funds can be stolen. If it’s lost, funds can be unrecoverable. For deeper guidance, follow the information provided on BitAddress.org.
Step 4 — Configure Wi-Fi & Mining Settings (Important)
After connecting to the setup network and opening the configuration page, you will see many technical fields. You only need to focus on the items below.
1. Configure Wi-Fi
• Tap Configure Wi-Fi
• Select your home network (Wi-Fi must include the 2.4 GHz band)
• Carefully enter your Wi-Fi password
2. BTC Address (Primary)
Paste your Bitcoin receive address here.
3. Pool URL (Primary)
Delete what is there and paste:
stratum+tcp://public-pool.io:3333
4. Pool Password (Primary)
Type the letter: x
5. BTC Address (Fallback)
Paste the same Bitcoin address again here.
6. Pool URL (Fallback)
Paste this as backup:
stratum+tcp://solobtc.nmminer.com:3333
7. Time Zone (Optional)
Select your UTC.
Tap Save and wait 10–15 seconds. The device will reboot automatically.
Do not use the default pool shown on the page. Some units may ship with outdated pools that do not work.
Do NOT change these (Recommendation)
Leave these exactly as they are:
• Pool Password (Fallback)
• DeviceCode / License
• UI refresh / Brightness / Screen options
Step 5 — Confirm Mining Activity
After reboot, the display will show live stats: hashrate, difficulty, shares, and connection status.
You can verify your miner is working by searching your Bitcoin address on a pool explorer:
Paste your BTC address into the search bar on either site to see live share activity from your device.
Step 6 — You’re Done
If you followed all the previous steps, your Kryvado is now mining.
You can tap on the screen to cycle through different pages showing different live information from the miner.
⚠️ Important Requirements
• Device only connects to 2.4GHz Wi-Fi (not 5GHz).
• Stay within 3–5 ft during initial setup.
• Use a proper USB power source (weak ports cause boot loops).
Buttons (Back of Device)
The device has two small buttons on the back, located next to each other (small labels next to the buttons):
• RST (Reset): Press once to restart the device.
• BOOT: Used for configuration mode and display controls.
BOOT button actions:
• Long press: Enter miner configuration mode
• Double click: Switch to next screen page (if display available)
• Single click: Wake the screen (if display available)
Tip: If something freezes during setup, press RST once to reboot and try again. Avoid holding BOOT unless you intentionally want configuration mode.
Troubleshooting Common Issues
“nmap-2.4g” Wi-Fi does not appear
• Unplug → plug back in to restart setup mode
• Stand closer to the device
Stuck on “Connecting…”
• Check Wi-Fi password carefully
• Ensure network is 2.4GHz
• Power-cycle and retry
Screen is blank
• Tap the power button to wake display
• Check brightness in settings page
Pool connection issues
• Some routers (ASUS with AI Protection) may block mining traffic — temporarily disable
• Try a different BTC address format
• Change pool to: pool.nerdminers.org : 3333
Monitoring & Management
If you’re running more than one device—or you want deeper visibility—NMMiner supports two monitoring tools. Both let you find miners on your network and manage settings more efficiently than the on-device portal.
NMController Client (Windows)
A Windows desktop app for discovering miners and configuring devices in bulk.
- Automatically scans your local network to find active miners
- Group configuration (useful when you have multiple devices)
- Same functions as the web version
NMController Web (Windows/macOS)
A cross-platform option that provides similar controls through a browser-based workflow.
- Works across Windows and macOS
- Find and manage devices on your network
- Best if you don’t want a Windows-only app
Web-based monitoring (single device)
You can also access a built-in web monitor by opening your miner’s IP address in a browser. It’s useful for quick checks and basic device info.
How to open it
- Find the miner’s IP address on your router’s device list (or in NMController)
- Type the IP into your browser (example: http://192.168.1.120)
- You’ll see live status similar to NMController
Note: Bulk configuration features may require newer firmware (v1.5.xx or later). If something looks missing, update firmware first using the Flash Tool.
Firmware Update (Fixes pool & connection issues)
Kryvado uses the ESP32-2432S028R (2.8" display) with ST7789 driver.
If the device fails to connect to pools, stays on “connecting…”, or behaves strangely, updating the firmware resolves this.
Open NMMiner Flash ToolWhen you click Connect, your browser will show a USB/Port selection popup. Make sure your device is plugged into the same computer you’re using for the Flash Tool, then select the device/port from the list to continue.
When asked to select your board, choose:
esp32-2432s028r-st7789
