The Beta1 version has a design with RGB gradient lights, but the 5v part needs to be attached separately. The dcdc part uses TPS62130. It can be attached according to the schematic diagram in the specification. The feedback resistor is replaced by a potentiometer. In theory, it is 20-50k can be used

It is strongly recommended to dissipate the heat of the array card and add a small fan. The air ducts of ordinary household chassis are not enough to take care of the array card. Over time, the card may hang or become unstable.

2022-4-23 Remaining: Beta3 has slightly modified the wiring of the power supply part, reserved the 5V input part, and removed the LED light-emitting logo. When there is time, a version with LED gradient will be added. The board is still on the way, and it will be added when it is available. Physical map.

2022-4-28 Stay: Verified that Beta3 board is available

2022-4-28 Stay: The heat sink can hold two 3cm small fans, which is just right. This card generates a lot of heat, so be sure to dissipate the heat properly to avoid unnecessary losses.

All merchants and stores recommended here have no interest relationship with me , are not advertising , and do not guarantee the quality of the work!

1. OCP connector socket: I bought it from Shenzhen Hongyutong Electronics Store in Shenzhen. You can find it by searching for BTB connector board to board. When placing an order, just select 120P-female socket-3.7H. I will buy it. When I placed the order, it was 4.8 with free shipping. After searching on various platforms for an afternoon, I found two that sold 4.8. This one had the highest sales, so I bought this one. So far, I have received the goods without any problems.

2. Copper pillars and fixing screws: Just buy copper pillars with a height of M3*8mm. Remember to buy double-pass ones. Baobao basically costs 4-5 yuan for 50 pieces with free shipping. The height of 8mm is matched with the 3.7H specification above. For connectors, if it is a connector of other heights, please purchase copper posts of appropriate height. The screws I bought were M3*4 Torx screws, which cost 50 each for a few bucks. They were very cheap. I personally think the countersunk head Torx screws are more beautiful than the cross ones, so I bought the Torx screws. You can buy them according to your needs here. The length of the screw is recommended to be M3*3 or *4.

3. Baffle part: I shopped around for this on a certain store, and the prices seemed to be in the 5-6 range, but they didn’t come with free shipping. Buying one or two was not cost-effective for shipping, so I didn’t buy it if I didn’t think I would use it. .

4. Capacitors and resistors: Just buy them according to the needs of the board or the recommended parameters given in the specification.
