Why do I need Solo Miner

Why do I need Solo Miner, first we need to know what is Bitcoin Mining, and what is the difference between Solo Mining and Pool Mining.

The NM-RF-HAT is designed as a companion hat for ESP32-2432S028 CYD device. Support Bruce firmware, and other RF application with ESP32.

When you start using the CC1101 function, you will follow the steps below.

Set the DIP switch to position 1 and select the RF option.
Choose the Config option.
Select the RF Module option.
Pick the CC1101 option.
Then return to RF menu to use other CC1101 functions.

2.3 NRF24

Set the DIP switch to position 2 and select the NRF24 option.
Select the NRF functions (such as Spectrum, NRF Jammer, or CH Jammer) as needed.

2.4 PN532 NFC

When you start using the RFID/NFC function, you will follow the steps below.

Set the DIP switch to position 3 and select the RFID option (Config -> RFID module -> choose PN532 on I2C).
Select the RFID functions (such as Read tag ) as needed.

2.5 RF 433M – OOK/ASK

When you start using the RF 433M -OOK/ASK function, you will follow the steps below.

Set the DIP switch to position 5 and click the RF option.
Select the Config option.
Select the RF Module option.

Return to the config menu and select the RF TX Pin option.
Select the M5 Pin 22 option.
Return to the config menu and select the RF RX Pin option.
Select the M5 Pin 27 option.
Then return to RF menu to use other RF433 functions.

2.6 IR Controller

When you start using the IR controller function, you will follow the steps below.

Set the DIP switch to position 4 and select the IR option.
Select the Config option.
Select the IR TX Pin option.
Select the Pin 22 option.
Return to the config menu and select the Ir RX Pin option.
Select the Pin 27 option
Then return to IR menu to use other IR functions.

2.7 GPS

When using the GPS function, you need to connect the GPS module first, and then follow the steps below to operate.

Select the GPS option ( the official firmware changed default pins to RX=22 TX=27, for nm-rf-hat change to RX=1 TX=3)
Select the GPS function such as GPS Tracker/Wardriving
