CANable: A small, low-cost, open-source USB-to-CAN adapter based on stm32f0

CANable 2.0 is a small, low-cost, open-source USB to CAN adapter. CANable enumerates as a virtual serial port on your computer and acts as a serial line to CAN bus interface. Using the alternative candleLight firmware, CANable enumerates as a native CAN interface on Linux. CANable 2.0 supports standard CAN and CAN-FD.

The CANable adapter is compatible with ARM-based embedded platforms such as Raspberry Pi, Raspberry Pi Zero, ODROID, BeagleBone, etc., making it ideal for integration into OEM products.

syzygy-sgmii: Breakout board for SGMII Gigabit Ethernet PHY DP83867C

This design is a breakout board for SGMII Gigabit Ethernet PHY DP83867C. It connects to SERDES via a SYZYGY-TXR connector to test and evaluate Ethernet over 1.25Gbps serial channels. 2 channels are used and CDR is required on the RX path. Compared to RGMII, SGMII significantly reduces the number of signals required for routing.

Open source lithium battery management board, charging 5V2A, discharging 5V/1.52A or 12V/0.76A

This DIY LiPo super charger can charge a single LiPo battery and protect it from overvoltage, overload and short circuit. In addition, it can boost the battery voltage to 5 V or 12 V. The boosted output voltage is protected by an "eFuse" IC with a maximum output current of 1.52 A at 5 V and 0.76 A at 12 V. The charger part of the circuit requires a +5V power supply, which can be connected via USB-C, or simply solder two wires to pads on the PCB. Additionally, other connections can be soldered to pads on the PCB or use individual pin headers.
