When you are wiring a combat robot instead of using a flight controller, there's no easy interface for the standard 8-pin connector found on many of these ESCs. Well, at least not until now!\u003cbr\u003e\u003cbr\u003eIntroducing the BETA V0.3 Blueson A1 Backpack PCB. This board features a 36V tolerant linear voltage regulator capable of powering a standard ELRS receiver with up to 6S LiPo input (or 8S with added cooling - this may be addressed in future versions). \u003cbr\u003e\u003cbr\u003eThis backpack PCB handles several important functions. \u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eProvides a breakout of the 8-pin to helpful labeled pads\u003c\/li\u003e\n\u003cli\u003eHas an onboard power LED and voltage regulator to convert battery voltage to 5V for a standard RC receiver\u003c\/li\u003e\n\u003cli\u003eHas a 6 pad breakout of the ground, 5V and motor signals to a secondary PCB\u003c\/li\u003e\n\u003cli\u003eThe secondary PCB has a set of 12 holes perfectly aligned for an ER4 (or R84) receiver to slot and solder in place, allowing for a compact right-angle sandwich board construction\u003c\/li\u003e\n\u003cli\u003eMatching 20x20mm M3 mounting holes allow for the whole board to act as a 'backpack' when combined with a Blueson A1 ESC and a suitable 3D printed spacer (not included). \u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0764\/3129\/4773\/files\/Blueson_A1_4in1_ESC.step?v=1781709940\" title=\"cad mockup\"\u003eV0.3 CAD download available here.\u003c\/a\u003e Note this is a rough approximation CAD for the ER4 receiver, spacer, and total board arrangement.
