V+ connection from the ESC to FC will typically carry VBAT voltage direct from the battery connection. The ESC V+ connection is an Input Voltage to the FC whilst RX, GPS and other connectors' V+ pads carry output from the FC's onboard voltage regulators. In some cases VTX or camera connectors may offer VBAT voltage directly but due to voltage fluctuations induced by the motors the use of VBAT direct to VTXs or cameras is discouraged. To minimise the risk to sensitive VTX hardware it is advisable to provide an additional high voltage regulator for such components. Recommended continuous power draw for this high voltage VTX regulator is ~18W, translating to at least a 9V/2A part, and output voltage should be between 8-12V, preferably 10V. +#### Standard ESC Pin Configuration + The pin configuration for the JST SH connector is as follows: | Pin # | Signal Name | Description | @@ -59,6 +60,35 @@ The pin configuration for the JST SH connector is as follows: | 7 | Signal 3 | Motor 3 | | 8 | Signal 4 | Motor 4 | +#### ESC with additional power requirements + +An additional 2-pin connector for power (ext. power) can be used for high-powered devices or if the user wants to use an external power source. +Alternative a 10-pin connector can be used: + +| Pin # | Signal Name | Description | +| :---- | :---------- | :---------- | +| 1 | V+ (VBAT) | Power | +| 2 | V+ (VBAT) | Power | +| 3 | GND | Ground | +| 4 | GND | Ground | +| 5 | Current | Current | +| 6 | Telemetry | Telemetry | +| 7 | Signal 1 | Motor 1 | +| 8 | Signal 2 | Motor 2 | +| 9 | Signal 3 | Motor 3 | +| 10 | Signal 4 | Motor 4 | + +### Remote Control Link Pin Configuration (CRSF, ELRS) + +This receiver has the following standard pinout: + +| Pin # | Signal Name | Description | +| :---- | :---------- | :---------- | +| 1 | GND | Ground | +| 2 | V+ (5V) | Power | +| 3 | Signal 1 | RX | +| 4 | Signal 2 | TX | + ### Serial (UART) Pin Configuration (RX, GPS, and other 5V serial devices) The pin configuration for the 4 pin JST SH connector is as follows: From cbe4b0708abf6bc5c333ed7966794994830177f0 Mon Sep 17 00:00:00 2001 From: Mark Haslinghuis Date: Fri, 25 Apr 2025 02:48:06 +0200 Subject: [PATCH 2/4] Add note about connector color and legacy provisions --- docs/development/manufacturer/connector-standard.md | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/docs/development/manufacturer/connector-standard.md b/docs/development/manufacturer/connector-standard.md index c079b6926a..78d9173972 100644 --- a/docs/development/manufacturer/connector-standard.md +++ b/docs/development/manufacturer/connector-standard.md @@ -27,6 +27,11 @@ To address this, we have established a standard for drone connectors designed to Any harness should be widely available and easy to obtain.
