Got another different Blacking based PMP…

and I’m almost ready to start messing with Blackfin family finally. This PMP (also known as BlackHawk, IPad, or “Portable Media Player”) is hardware compatible with Gemei X720 PMP if I’m right, and features:

- BF531 @ 400 MHz (ADI BF531 SBST 400)
- 16 MB SDRAM (ESMT M12L128168A-LZV1P51HQ)
- 1.3 mpixel CMOS camera (crap quality! like a webcam xD)
- 3.6″ LTPS TFT (same brightness than 301’s LCD but worse contrast maybe)
- 1 GB flash (Hynix HY27UUD88G5M 727A)
- SD support (SDHC not likely to work with the default old 6.2.80 firmware)
- 2 speakers (higher quality than 301’s speaker)
- Nice d-pad and button layout (including crap L/R buttons)
- Gizmondo alike case skin.
- Other parts include PHILIPS FD1USBD12 (USB controller), XILINX XC2C32A VQ44AMS0545, and a 28-pins sanded mini-chip :(

Price was slighty cheaper than 301’s: 89 eur including shipping and VAT.

Just got my JXD 301!

Ah, finally! And does it worth its money? Absolutely yes.

Here you have my first impressions:

- Very nice: screen resolution, brightness and wide angle of vision. handheld light weight. quality beyond common chinese PMPs. firmware quite solid. handheld specs. sound quality through headphones. 2 jacks in a single handheld. sd support (probably SDHC too). 2 Gbytes Flash RAM. extras (headphones, usb cable, usb adaptor, velvet-ish bag case). extras from mp4nation (very well packed, copy from ainol firmware english instructions, european jack voltage adaptor, total price including VAT and shipping costs is 92 eur, declared for customs as usb drive/gift/100$ value).

- Nice: quality through speaker. buttons responsiveness.

- To improve: buttons layout, d-pad style (not *that* bad though), delivering time (17 days waiting for it!).

- What’s wrong: number of buttons, no L/R buttons, emulation and movie software quality (might be much better), audio white noise when using headphones and reading from disk (it seems a software/firmware issue to me).

And here you have some photos done with JamQue’s mobile (thanks man!):

A nice new toy

I came across a new handheld/PMP yesterday while surfing the net: the JXD301, featuring a 600 MHz (!) BF533 CPU, probably 64 Mb RAM, 2 GB flash, SD support, 3.0” awesomely bright TFT, rechargeable battery, 2 headphone jacks, DIVX/FLAC/APE/WMA/MP3/OGG player and 90 eur shipping and VAT included. Yes, a 90 eur bargain. It seems a good candidate for my xmas present to me, isn’t it?.
