Matek G474-HELI and G474-HLITE¶
Both use the MATEKG474HELI board when flashing.
G474-HELI¶
| Board | MATEKG474HELI |
| MCU | STM32G474CE |
| Gyro | ICM-42688-P |
| Blackbox | 128 MB flash (W25N01G) |
| Barometer | SPL06 |
| Servo outputs | CH1-CH4 |
| Motor outputs | M1, M2 |
| RPM input | Frequency input |
| UARTs | UART1, UART2, UART3, UART4 |
| Other | LED strip, buzzer, USB-C |
| Battery input | VBat 2-6S (5.4-30 V) |
| Onboard BEC | 5 V or 7.2 V selectable, 5 A (8 A peak) |
| Size, weight | 38 × 26 × 13 mm, 15 g |
Onboard BEC¶
The servo BEC is powered from VBat and gives 5 V by default, or 7.2 V with its solder bridge closed.
External BEC
If you power the servos from an external BEC, the onboard BEC must be disabled with the Vx Off solder bridge.
G474-HLITE¶
A smaller version without the onboard BEC.
| Board | MATEKG474HELI |
| MCU, gyro, blackbox, baro | As the G474-HELI |
| Servo outputs | CH1-CH4 |
| Motor output | M1 |
| UARTs | UART1, UART2 (RX only), UART3, UART4 |
| Vx input | 4.5-14 V |
| Size, weight | 30 × 23 × 13 mm, 9 g |
Motorised tail¶
The HLITE has one motor output. For a motorised tail, turn servo 4 into motor 2:
resource SERVO 4 NONE
resource MOTOR 2 A06
