Osc dev v006
About the Osc dev v006 PCB
Osc dev v006 is an open source STM32 PCB design by OpenServoCore, published on GitHub under the Apache-2.0 license. It is a 6-layer board measuring 50 × 40 mm, with 82 components from 39 distinct parts.
Its main chip is the STM32F301K8UX, from the STM32 family. Other key parts include the DRV8231ADSGR and SSP7615-33DFR. By type, the board carries 11 connectors, 4 LEDs, 3 ICs, 1 jumper and 1 resistor.
It belongs with the robotics & motion and power & battery designs in this gallery.
From the project
The goal of this project is to create an open servo controller board and firmware.
This is the OpenServoCore firmware development and validation board. It is built around the CH32V006F8P6 and designed to accept any gutted hobby servo (SG90, MG90, and similar), so firmware can be brought up and characterized against real motor / pot / encoder hardware.
The render predates the 2A refresh, so the connector set on it is one revision behind the schematic.
