@SnoopKatt Only supports the main board with on-board SDRAM.

@zyjnumber1 Does it use the baseline QMTech MiSTer boards, or does it require a custom version?

QMTECH Mister Handheld IO V0.1😁😁😁 LCD: 800x480 Battery: 3000mAh(Charge 5 hours, play 2 hours🤣)

@PixelCNinja I will have to redesign the main board to get HDMI and LCD output simultaneously‌. This V0.1 Handheld IO board only supports the existing main board with on-board SDRAM.

@zyjnumber1 Can it be played via mains, does/will it have video out too?

@ackiesruth PCB space is very limited. No idea yet. :)

@zyjnumber1 Possible to have it on V3?

@ackiesruth No composite circuit. Our new board's A/V part circiut is following the Mister official V9.2 IO board and AV board V1.2

@zyjnumber1 Is there a circuit built in to support composite? Combine luma+chroma.

@PixelCNinja 😀 Thanks~ Here is the link of QMTECH Mister: aliexpress.com/item/100500785…

@zyjnumber1 Thanks, someone mentioned this over on one of the discords, maybe even mine. I'll highlight this issue in the weekly news video, tomorrow. Could you please provide me the exact link to your AE store?

Recently, I've got several complaints from buyers regarding the QMTECH Mister quality issues. Like poor soldering quality or cores like PS1 and N64 are not working. I'm here to clarify these boards are direct clones of our QMTECH Misters. Please be careful when place orders.

QMTECH only sells Misters in their official store. No other distributors from China. Our official link for Mister is here: aliexpress.com/item/100500785…

@thefollow_c yes. battery charged handheld device. The HDMI port is not available for this version.

@zyjnumber1 Will it only be portable mode or will there be an option to use it via HDMI in some cases as well? Will we have a battery?

Good News: A new IO board for handheld application is almost ready. Verifying.. Bad News: Only support the QMTECH Cyclone V Board with on-board SDRAM. The manufacture plan will be delayed due to the chip price goes unreasonable recently. Blame the trade war between US and China.

@FPGATV For this version, the HDMI port is covered by the enclosure. So only LCD display available.

@zyjnumber1 Can you output video to the screen and to HDMI at the same time for streaming purposes?

@PixelCNinja @whatskenmaking 😀I can say this handheld IO board is inspired by @whatskenmaking's design.

@zyjnumber1 This is cool. Is this based on @whatskenmaking's design?

@StonedEdgeMods Got it. Thanks. So the enclosure is 3D-printed case. Not a plastic one.

@zyjnumber1 Sure, the project is available here github.com/StonedEdge/Ret…

Cooking up something from PCBway…

@StonedEdgeMods can you please share the link of this enclosure. I'm really interested in this. Thanks

@zyjnumber1 Yes it is

@Matt_Volk I'm afraid it won't

@zyjnumber1 Does the Retrocastle IO board work with the FPGA board you sell?

Simple and quick update. IO board and case(made of PCB) are ready now. Stock will be renewed daily. Price for IO Board only: $25.9 Price for IO Board and Case: $29.9 aliexpress.com/item/100500763…

@jaeofmercia @antoniovil provides IO board with RGB888 video and pure I2S audio. Please contact him if you are interested.😀

@ricardosaraiva looks very cool!👏👏

@zyjnumber1 new UltimateMiSTer Lite I/O Board and aluminium case coming for your new QMTECH compatible #MiSTerFPGA boards. /ricardo

@jaeofmercia any reference design for this 24-bit analog output?

@shiver_169 25mm x 25mm heatsink with fan. heatsink can be sticked to the FPGA chip.

@zyjnumber1 Ok thanks. One last question, what type of fan is used with the IO Board and how is it attached? so I can buy the appropriate ones.
