Lubancat 0W UPS Power Supply
Raspberry Pi Zero2W UPS power supply module based on IP5310
Preface:
During the development of the animal-themed movable eye system, I used the Luban Cat 0W. However, the Cat 0W's USB-C port was on the side, making it too small to fit, and there wasn't a suitable boost power supply module (dragging a power bank along would be too abstract).
Therefore, I created this integrated power supply module, which combines charging and discharging. I initially considered buying a ready-made UPS board
from Taobao
, but the price was 128 RMB and only available in Raspberry Pi-sized versions, which was prohibitive. So, I created my own
reference design using a similar approach. It uses spring-loaded pins to connect the power supply pins at the GPIO and the I2C interface to the Cat 0W.
Modifying the board size allows for compatibility with the OrangePi Zero2W and Raspi Zero2 2W series, as well as other similarly sized development boards
(for the Raspi Zero2 2W, see another dedicated project that integrates a docking station, power supply, and eMMC module).
The current discharge status can be read via the connected I2C interface (please purchase the IP5310-I2C version).
Library files and register manuals are also included. Thanks to the link to the attachment from the user "youli".

Cooling cup holder
An H-bridge circuit is constructed using four MOSFETs and their gate drivers to control the forward and reverse rotation of the thermoelectric cooler, enabling heating/cooling.
The power supply employs a PD decoy circuit, directly using a Type-C port for 12V power.
Two thermistors are also included to read the temperatures of the hot and cold surfaces.
The PD decoy circuit verification failed; regardless of the resistor matching, it only outputs 5V. I plan to redesign the board and use level control for the output voltage.
Below are the temperatures at room temperature, heating, and cooling.

Low-cost server intelligent power supply CSPS-ATX
Using a standard server power supply, the system communicates and networks with the power supply via the ESP8266, enabling control of the power supply's start/stop, data display, and integrated remote start/stop control via computer.
Project Background: This project
aims to build a mini secondary PC using existing, old, and unused computer parts. A low-cost, small-sized power supply is needed, and a relatively reliable second-hand server power supply was chosen.
Project Reference:
[wuyu无语] Huawei 460W CSPS Power Supply esp8266 Smart Power Supply Board
CSPS-ATX12VO Smart Power
Supply Specifications:
Model: PS-2461-16H-LF
Input: 100-240V~50/60Hz 6-3A
Output:
+12V38.3A MAX
+12VSB2.5A MAX
Maximum Output Power 460W
Manufacturer: Lite-On Technology Co., Ltd.
This power supply has passed CCC certification and is 80 PLUS Platinum Standard.
Project Description:
1. The power board uses a 12VSB voltage, which is stepped down to 5V using a TPS563201DDCR DC-DC controller. This 5V powers the computer as its 5VSB voltage. An ASM1117 further steps down the voltage to 3.3V to power the ESP8226 microcontroller.
2. The ESP8226 communicates with the power supply via IIC to read power data (IIC operation address is in the power supply manual).
3. The ESP8226 uses an HTTP service to display the read voltage, fan speed, and power consumption, and allows for power supply control via a web interface
. 4. The ESP8226 controls the AQV252GA to perform power on/off operations, enabling remote power on/off.
5. The ESP8226 has a reserved interface via IIC for connecting an external OLED screen to display power data.
6. The power board has one DC connector and two XT60 connectors. The DC connector can be used to power the monitor, reducing the need for a separate DC adapter. The XT60 connectors are used to connect the core board and graphics card.
7. The PCB is a 4-layer board, and it should be able to handle 750W without any problems. Currently, I only have a 460W power supply for testing.
Note: For replicas, the shorting point does not need to be soldered. This shorting point is for use without the ESP8266, directly using 12VSB
for testing:
using an E3 1231V3 + B85, P600 graphics card, a 30-minute stress test, no problems. It has been working normally for 3 months. The difference between this test version and the above versions is that this test version does not have remote power-on functionality.
