| Memory | 1, 2, 4, 8 GB LPDDR4-3200 RAM (shared with GPU) | 2GB/4GB/8GB (LPDDR4/4X) |
| Network | Ethernet: 10/100/1000 Mbit/s Wireless: b/g/n/ac dual-band 2.4/5 GHz Bluetooth: 5.0 | Gigabit Ethernet Wi-Fi 5 + BT5.0, supports BLE |
| Multimedia | GPU: Broadcom VideoCore VI @ 500 MHz HDMI: micro-HDMI | HDMI 2.0 |
| Peripheral Devices | 17× GPIO plus the same specific functions, HAT, and an additional 4× UART, 4× SPI, and 4× I2C connectors | USB2.0/3.0 M.2 M-KEY interface (optional) |
| Power Supply | 5 V USB-C input, or GPIO port input | Type-C power supply |
| Operating System | Linux NetBSD OpenBSD Plan 9 RISC OS Windows 10 ARM64 Windows 10 IoT Core NixOS | Supports Android 11, Ubuntu 22.04, Ubuntu 20.04, Debian 11, Debian 12, OpenHarmony 4.0 Beta1, Orange Pi OS (Arch), and other operating systems based on OpenHarmony (OH) |
Price Comparison
| Memory | Orange Pi 3B | Raspberry Pi 4B |
|---|---|---|
| 1GB | / | 298 yuan |
| 2GB | 229 yuan | 358 yuan |
| 4GB | 279 yuan | 398 yuan |
| 8GB | 335 yuan | 538 yuan |
Orange Pi 3B can serve as an alternative to Raspberry Pi 4B
Previously used scenarios for Raspberry Pi 4B, such as Home Assistant, Ubuntu Server, etc., can now consider switching to Orange Pi 3B
There are mainly 2 irresistible reasons
-
With similar configurations, it is relatively cheaper by more than 100 yuan, showing a clear price advantage
-
Orange Pi 3B has M.2 M-KEY interface, which can connect NVMe M2 SSD
As shown in the picture below
-
A 128GB (2230 model) (69 yuan)
-
A 512GB (2242 model) (170 yuan)
Note: The copper pillars for fixing the SSD need to be purchased separately; Orange Pi 3B only has fixing holes without corresponding nuts and screws
The above reasons for hardware transition to an alternative; if there were no software issues, there wouldn’t be a sudden switch to Orange Pi 3B
Raspberry Pi 4B 2GB uses a TF card to install Home Assistant smart home (via firmware flashing)
After not using it for a while, it reported an error upon restart
The system is unhealthy, installation failed
Indicates failure in update/install calls
Considering using Docker to run Home Assistant, this way, there’s no need to flash an entire system, allowing for simultaneous deployment of MQTT, FRP, and other smart home services
Home Assistant deployed using Docker does not show the options in the red box in the picture below
Configuration -> Add-ons -> Run additional applications around Home Assistant
That is, Home Assistant Supervisor
Add-ons, refer to the picture below
Can be understood as the official application store; this article mainly wants to use ESPHome
Convenient for connecting ESP, for temperature and humidity, cameras, and other devices
After switching to Docker deployment, I found that ESPHome can also be deployed using Docker
It can also connect devices
The picture below shows Docker ESPHome connected to Docker Home Assistant
Connected devices include ESP32+DHT11
After the battery of the Xiaomi temperature and humidity meter ran out, the DHT11 temperature and humidity has been stable for 3 days
Paired with Home Assistant, it is possible to clearly see the history and current status
Once the configuration of MQTT and others is completed, additional interaction scenarios can be set up
