Hi there. Any one have Schematic of LeMaker Guitar CPU Module? I found on a YouTube Video it was available before on official site download section but not available now. Only the Guitar Base Board Schematic now available. It will be very helpful if anyone can share. Thanks in advance. Regards.

Hi All. I have some confusion on Touchscreen interface. My ques is very basic on LCD interface types ... apologies for that. I like to use a 3.5" Touchscreen. For CPU either Allwinner H6 and RK3328 is in my choice. I have attached the Touchscren Datasheet. Here we will build a custom PCB for the Touchscreen. But I found RK3328 don't have any LCD Interface. So is there any possible way to use this Touchscreen with RK3328 based SBC like Rock64? On the other hand Allwinner H6 have RGB LCD port. But in Touchscreen Datasheet it said LCD Driver IC is ILI9488. As H6 have direct RGB Port so do we need to use this ILI9488 Driver? There are many Touchscreen Shield connects with GPIO Header ... how they are communicating without a dedicated LCD Interface? Thanks in advance. Regards. HT035K1HV50C-U-V0.pdf

Hi Thanks. Sorry for my typo on 3329. I mean 3399. Great to know about SOM204. But it will be long time to wait till 2019. Do you know how the performance of 3328 Boards like Rock64 for USB 3.0 Data? Regards.

Thank you very much for reply. I personally more biased with RockChip than Allwinner. However, I did checked the prices of CPU's but 3329 is very expensive and it gets exceed or target BoM cost that's why I am more like to use 3328. But surely I agree 3329 in current trend and resource, support is more rich. How will be to use 3328 you think and If I consider my development based on Pine64's Rock64 or Firefly's ROC-RK3328-CC? Regards.

Hello All. I am fairly new in Embedded Linux and in this forum. I need to develop a small size IoT ARM Quad Core Board. I like to have some advise on my project's proper development path. First let me share my target needs of the project: -1. ARM CPU (run Linux) - I think for my project, Quad-Core is more than enough -2. RAM 1GB/2GB -3. eMMC 16GB for OS Boot -4. SD Card for file storage (up-to 512GB) -5. Two USB2.0 (One Host Mode and One Device Mode) and one USB3.0 (Only Host Mode is Ok. Its for faster file transfer to connected external Portable HDD) -6. Capacitive Touchscreen 3.5 Inch (as we will run some Python based GUI App) -7. Sensor connection via GPIO, UART, I2C, SPI (Sensors are Ambient Light, Sound, Motion PIR, 9-Axis MEMS Accelerometer, Gyro, Magnetometer) -8. Wireless including GPS, WiFi and Bluetooth 5.0 -9. Small Form factor (if find any Core CPU Module is great, else need to do custom PCB design) -10. Less heat generation Now based on the above spec USB 3.0 feature makes my choice very narrow as there are very few CPU supports USB 3.0. So far I am thinking about RK3328 or Allwinner H6. RK3339 will be great and more powerful but its very costly so don't wanted to use it. My ques are: - Based on my online research for start development I can use Orange Pi Lite 2 (in case of Allwinner H6) or Rock64 (for RK3328). But which one will be best choice for my project? In terms of implement features, easy of development, available online resource ... etc? - is there any Open Hardware project which I can consider as base of my study. All the available SBC's are open source and only Schematic is available. - Anyone know any small Core CPU Module (SMT or DPI) based on the H6 or RK3328)? Thanks. Looking forward your guideline. Regards.
