How to use GPIO or UART ports?

AlpDmr — Mon, 29 Apr 2024 20:56:56 +0000

Hello to everyone, I am newbie on Elecrow HMI Displays and I have a probably a simple (for you sure) question.
Suppose I have any sensor/board that uses GPIO port or UART interface of an HMI display, can I use this sensor/board with only using Elecrow's ports over or do I need to use an extra device with microprocessor?
If so, is there any tutorial/video/documentation about using Elecrow HMI Displays with hardware? Because nearly all tutorials are just about the design of HMI with SquareLine Studio and compile to Arduino IDE.

CrowView Note - Battery died!

lyx — Sat, 25 Jan 2025 01:09:02 +0000

I received my CrowView Note in November 2024 and it was working fine then. Battery was able to last at least a few (2-3) hours. When turning on the device after a month or so, battery is empty so the device is charged. But after a long time (3-4 hours), the device can only turn on for about 10 seconds before turning off. When checking the charging indicator above INSERT key, it turns off after a few minutes of charging and display shows a green full battery. However, the device can only power on for about 10 seconds before turning off again. Please help me

🌟Elecrow Dropshipping Service, a Game-Changer for Partner Sellers!

Erin — Fri, 25 Apr 2025 02:21:03 +0000

Hey everyone! We launched an incredibly seller-friendly dropshipping service—Elecrow Dropshipping—and I can’t wait to share it with you! If you’re running an online store or selling on platforms like eBay or Tindie, dealing with PCBs, electronic components, or creative hardware products, this service is definitely worth checking out. Here’s my take on its key features and experience, based on our website (https://www.elecrow.com/dropshipping.html).

💡What is Elecrow Dropshipping?
In a nutshell, the Elecrow dropshipping service allows you to sell without holding inventory. You just pass the orders to us, and we handle everything from packaging to shipping—super convenient and efficient! It’s a lifesaver for sellers who want to focus on product development, marketing, or customer service.

Key Features:

📦End-to-End Dropshipping:
Once you receive an order on your store or platform, simply forward the order details to Elecrow (or place it directly on their website). We pick the products from their inventory, pack them, and ship them directly to your customers. It covers all products on its website and even supports electronic products or samples from your store—very flexible!

💰Transparent Pricing:
Dropshipping fee formula: Shipping cost × 1.1 + $1.5.
This fee includes packaging materials (bubble bags, cartons, etc.) and labor costs (dedicated packers and address verification). Costs are calculated based on product weight, shipping method, and destination, and you’ll know the exact fees before paying—no surprises.

📬Global Shipping Support:
Elecrow has an advanced warehousing and logistics system, prioritizing order processing for quick turnaround. We offer international shipping services, delivering to customers worldwide while keeping shipping costs as low as possible—great value for money.

RC050S Fan Connector

Hyperion0 — Wed, 27 Nov 2024 13:50:04 +0000

I need to replace the fan for my RC050S, but I can't find any information about what the fan size is or anything.
Strictly speaking the fan still works, if I can get the correct size jumper for the board, but again I can't find any information on the fan or what size jumper I would need to reconnect it.
Does anyone have any info or details?

Battery charging circuit on 7"

sgruby — Mon, 12 Feb 2024 21:06:45 +0000

Is there any kind of information on the battery charging circuit on the 7" HMI?

How large a lithium battery can I connect to it?

What is the charging rate?

Is there any way to know if the battery is fully charged?

Thanks.
