DockerPi Series IoT Node(A) Board for Raspberry Pi 4B

About: I am a linux fan, a maker, a boy who like make thing and have fun with my friends.

Descriptions:

IoT Node(A) is one of Docker Pi series module.

IOT Node(A) = GPS/BDS + GSM + Lora.

I2C directly controls Lora, sends and receives data, controls the GSM/GPS/BDS module through SC16IS752, the mainboard only needs I2C support.

Support Raspberry Pi and other similar products.

Features:

· Docker Pi Series

· Programmable

· Control directly (without programming)

· Extend the GPIO Pins

· GPS/BDS Support

· GSM Support

· Lora Support

· Can Stack with other Stack board

· Independent of the mainboard hardware (require I2C support)

Official Compatibility Test

Not only support the following development boards, other development boards can be compatible if they have I2C peripherals. (Note: some software changes may be required)

Raspberry Pi series (4B/3B+/3B/2B)

Supplies:

1 x Raspberry Pi 4B /3B+/3B board

1 x DockerPi IoT Node(A) Hat board

1 x 5V@3A Power supply

1 x 16GB class 10 TF card (32GB will be good)

Step 4: Register Map

here is the register map and the description of the register.

0x01 - 0x10 Write Only.

0x11 - 0x20 Read Only.

It is recommended to keep the default unless you know the meaning of the LORA parameter.

·
L_SET(Write Only)

1. Write 1 to set parameters from 0x22 to LORA Module.

2. Write 0 not effect

· G_RESET(Write Only)

1. Write 1 to reset A9G Module

2. Write 0 not effect

· L_RXNE(Read & Write)

1. Write 1 cause error

2. Write 0 to clear

3. Read 1 means data has been received, please get the data from the register 0x11 - 0x20.

4. Read 0 means no data available now.

· L_SET(Write Only)

1. Write 1 to send data,please fill in the data in register 0x01 - 0x10 before send.

2. Write 0 not effect
