@"BI7ANY"#p22416 已经有成品套件了，不过套件外壳现在用亚克力版本，3d打印的还不太成熟！有需要可以私信我

精致，板正👍，做这么个盒子成本多少啊，大佬

请教个问题，淘晶驰的屏幕接线接口在哪？图上貌似没找到呃左上角的是3.3V供电的LOED屏幕借口吧？

@"BG9JFN"#p22412 左边陶瓷天线旁边会自己设计PCB打版就是好，楼主考虑做成品套件么

@"BI7ANY"#p22416 原来如此，感谢

@"yuzhou"#p22406 板子成本可高可低，最贵不超200不含（树莓派）

@"BG9JFN"#p22412 左侧type-c口上面那个就是，屏幕串口稍加改动直接可以和板子贴合

The Raspberry Pi looks great on its own.

yuzhou

Exquisite, well-made👍What would it cost to build something like this?

BG2FAS

yuzhou The cost of the board can vary greatly, but it will not exceed $200 (excluding the Raspberry Pi).

BG9JFN

Could you please tell me where the screen connection interface for the Tao Crystal is located? I couldn't find it in the diagram.
Is the 3.3V power supply interface for the LOED screen located in the top-left corner?

BI7ANY

BG9JFN Next to the ceramic antenna on the left.
It's great that it can be designed and fabricated independently; would the main poster consider creating a finished kit?

BG2FAS

BG9JFN The one above the Type-C port on the left side is, essentially, a slightly modified screen serial port that can directly align with the board.

BG9JFN

BI7ANY That's right, thank you.

BG2FAS

Acrylic finished enclosure

BI7ANY

BG2FAS Looks good.
Are there any bugs with the screen firmware?

BG2FAS

BI7ANY I use T135 for the screen, and there are many firmware versions available online for this model! I prefer to use WPSD, which has a full-featured driver for Micro Crystal screens, so once configured, I can use it directly without needing to flash the driver again.

BI4UMB

👍👍👍

BI7ANY

BG2FAS I'm using your firmware because I developed it, and I want to collect user feedback.🤣
Original post https://forum.hamcq.cn/d/1770

BG2FAS

BI7ANY Haha, so the original author of the screen firmware is here! I haven't actually tested your screen firmware yet. I sent a finished version of this "Akylic" version to a senior friend for testing! He should still be waiting for it. I'll ask him about his experience later!

BI7ANY

BG2FAS The only aspect of this design that concerns me is the cooling. With the current configuration, it easily reaches +50°C without a fan, but adding a small 2010-style fan at 50°C would automatically start, which would be more suitable for long-term use.

BG2FAS

BI7ANY Okay, I've considered that. There will be a separate pin on the board to provide power at 5V! I found a very thin fan made in Taiwan (available on Taobao) that is only 3mm thick, and it shouldn't affect the overall thickness.

BG0EQG

Do you have a 4G module?

BG2FAS

BG0EQG I didn't add it; adding 4G would increase the thickness, so I gave up on that idea!

BH2XJL

Where should I post the purchase link? I've reserved two.

BG2FAS

BH2XJL 再有就要8月中下旬了，产能有限😂加我qq：56766681
