M4 expansion board for use on BLDC quads - 0r3 black

[aBUGSworstnightmare]

Hi,

I've tested a new board house and now I have some matt black 0r3 PCB left for sale.

M4 uSD BLDC expansion board 0r3

Features of the M4 uSD BLDC 0r3 expansion board:
- 2S-3S LiPo supply (connection cable included)
- uSD card socket
- 5V LDO to supply i.e. RX or BT module (very handy when using KISS ESCs)
- radio (i.e. Bluetooth) connector with 5V LLC, use with 'Arduino compatible' BT-module (i.e. from flyduino). A ZHR-4 connector is included; interface cable can easily be made from Spektrum Sat cables.
- access to M5-M8 (motor outputs) for use with BLDC ESC
- LiPo voltage divider - used with Beta boards only (J1 closed, software as shown in the 'How-to'!
- M2 setnuts + plastic screws for fixing M4 on the expansion board

A lot of information - including details on the Software changes - can be found here: viewtopic.php?f=40&t=3857#p27004

Note: When using this board with the M4V2 production version Jumper J1 needs to stay open! The V2 version has dedicated inputs for LiPo voltage sensing!
Will show a wiring diagram for the M4V2 when I have it on hands.

The board sells for 25EUR (fully assembled and tested) + shipping (i.e. 1,45EUR in Germany). If your interested in the M4 expansion board send me a PM with your location and I will quote the shipping costs.

I can not PM as I dont have the authority to use this feature. Any chance administrator can upgrade my profile as I want to buy this board along with the M4 board that I brought yesterday.

Hi Joerg,

I have just entered the AQ world with the M4 and would like to buy one of your boards to move the M4 to a bigger quad. I have the same issue as ravenhaven (not being able to send pm's).

Could you please send me an PM?

Thanks,

Trondur
