I'll take inspiration from this..

https://forum.openwrt.org/viewtopic.php?id=34188

obviously it must be included inside the original plastic casing..

have U guys consider that Hame A1 wont have suficient power eficiency to power up 2 ports?

Surely that depends on what is connected. A webcam and a serial port should work, the same as if connected to an external passive hub, and many microprocessors powered by USB and communicating through the serial port. If you try to run big motors, that would be another issue.

I may have missed it when scanning back through this thread. Has anyone posted a link to the datasheet for the Ralink processor?

When used to generate 5V output, the Hame A1 step-up FP6290 switching voltage regulator is able to deliver up to 800 mA with a 90% efficiency (see datasheet).

So this is at least 1.5 negotiated full USB load or 8 non-negotiated USB loads.

But there may be some other limitations in the Hame A1 design itself.

Not available publicly

However, you can find a preliminary datasheet for the RT3050 which is quite similar.

Here seems to be another similar router, HAME A15, even a little bit cheaper ($17.51): http://www.ebay.com/itm/Portable-2in1-M … 53f243ea24

With the battery the MPR-A1 is a lot more interesting, would be nice to know if there are other differences.

What would be nice are a larger Flash/SDRAM (8MB/32MB) memory capacities, like what is proposed by swatfa, but I am not sure this one will have feature these...

Squonk--thank you for the datasheet link. Assuming similar pinouts for the actual chip, and your previous analysis that GPIO7 is USB power, would it be at least theoretically possible to tie USB power high, cut the trace to GPIO7, and then use the UART configuration shown below (GPIO7 is RTS_N) to provide a second, non-console serial interface?

(From page 17)

Of course, it would be preferable to tie "USB power" to a different GPIO. This might be a minimal board change which could add another useful feature.

Just to update, unfortunatly after talking to the factory the header modifications will not be done. Apparenty the research and development time to remap the new pcb is not possible for the time being for our expected initial order quantity. This would have to be kept for the next potential model or release of the product.

With this in mind is there any possibility that the device can still be used to interact with peripherals without the header? Im not very tech savvy but would it be possible just to use the existing i2c and free gpios to connect to the peripherals perhaps through soldering? I ask so that i can be sure whether or not i can mention that it is capable of communicating with devices/robotics etc in my marketing campaign or whether its impossible without the header discussed previously.

For now the confirmed upgrades are the 32mb ram and 8mb flash. Perhaps if the device can support larger flash than i will try to upgrade it even further. Will have to check the limitations of the uboot and compatible chips.

Sorry to hear that the "maker-friendly" modifications will not be possible. I hope some other manufacturer would be able to pick up the ball on this.

The device would be able to communicate with other devices via usb. Soldering to the board is also possible, and has been done by a number on this forum, but the contact points are tiny, fragile, and dispersed. For most, it would probably be easier to go with a device which has the GPIOs brought out, like the Raspberry Pi (which is quite powerful, but lacks wifi).

It would still be appealing to have one of these little devices, with wifi and perhaps a battery, which directly and easily supports GPIOs and I2C, an additional USB port, and a second serial port.

Price point would also be important for this device--considering the $25US price of the Raspberry Pi model A (with 128MB ram and SD but no flash and no case), and the $19 price of the unmodified versions of this device, a price of $25 would be attractive for a hobby-friendly, wifi-enabled "little computer" with battery.

I just got one MPR-A2 which is very similar but with a larger battery-5200mh.I want to open it and mod it with larger RAM.How can I gently open it without scratch its shell?

Any progress on this port?

Does someone have openwrt working on a model with 8mb flash? If so, can they post a link to a supplier?

This Flash is a GigaDevice GD25Q32 32 Mbit (4 MB) SPI Flash (see datasheet).

On MPR-A2 devices, the GD25Q64 Mbit (8 MB) SPI Flash is used (datasheet).

Here is a patch to apply to current trunk (revision 35016) to define both chips:

I bought on ebay for 15 € (more or less) a similar device Poray M3 (http://www.poray.com.cn/ch/product.asp? … 5108679705) some month ago , and I wonder if it's possible to build a OpenWRT image for my device. It's a RT5053F SoC based portable router (3G), but I'm not sure if your paches are compatible or not. I didn't test it because I have fear to brick it.

Didn't know this one yet

Could you please provide the source url and the price, please? It looks very interesting!

You can try to boot from SDRAM first by choosing option 1: this way, your original firmware is preserved. At least, you should have OpenWrt booting up to some point and eventually crash because it can't find the rootfs.

This way, you can verify that the Flash chip is recognized (it looks like a Winbond W25Q32 which is supported).

If you have access to a busybox shell in the original firmware, you can backup all your partitions to /tmp ramdisk using dd, and send them to your PC as a security using tfftp (you have to create the file on your PC first, it cannot be created during the transfer).

Once you verified that you have al lthe partitions backed up, you can try to Flash an OpenWrt image using uboot option 2, which will save it to Flash and erase the kernel+rootfs ONLY, not the uboot bootloader, so you can always revert to factory.

Thank you Squonk for the info. I have edited my original post. I will try the SDRAM option.

Yep, cheap as I said . I bought this one because it has SD & Micro-SD card readers , perfect for rootfs.
