NOTIFICATION
Recently we have noticed that there are fake F405-TE on market. If you are unsure if the F405-TE you purchased is genuine, you can send some high res photos of both sides of the flight controller board to service@mateksys.com. We will check out it for you.
Please purchase our products from authorized dealers https://www.mateksys.com/?page_id=1212
Tips
INAV, DSHOT can not work on S3, S5,S7 because of DMA clash, pls use ONESHOT or MULTISHOT and calibrate ESC PWM range.
This DMA clash will be fixed from INAV 7.x.x.
BetaFlight, set dshot_bitbang = ON when using X6 and X8 DSHOT.
BetaFlight, Target name was renamed as MatekF405TE_SD
ArduPilot, set LOG_BACKEND_TYPE = 1 (File) for SD card logging

| Mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs. If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group. |

- “Internal errors 0x4000 l:213 spi_fail” warining, pls set LOG_BACKEND_TYPE = 1 (File) for SD card logging.
- If sending highspeed serial data (eg. 921600 baud) to the board, use USART1(Serial1) or USART2(Serial6).
Frsky Smartport Telemetry
- non-inverted (hacked) S.Port signal
- any spare Uart_TX
- SERIALx_BAUD 57
- SERIALx_OPTIONS 7
- SERIALx_PROTOCOL 4 or 10(for yaapu)
DJI FPV OSD (ArduPilot 4.1)

- OSD_TYPE = 3
- SERIAL4_PROTOCOL = 33
- MSP_OPTIONS = 0 (polling mode)
Relay(PINIO)
- PINIO1, PIO1 pad, Low Level by default
- PINIO2, Camera switch, C1 ON by default
# GPIOs
- PA4 PINIO1 OUTPUT GPIO(81) LOW //PIO1 pad
- PB5 PINIO2 OUTPUT GPIO(82) LOW //camera switch
# RCx_OPTION: RC input option
- 28 Relay On/Off
- 34 Relay2 On/Off
- 35 Relay3 On/Off
- 36 Relay4 On/Off
e.g.
- RELAY_PIN 81 //PIO1 GPIO
- RC7_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to control PIO1 Low/High Level
- RELAY_PIN2 82 //Camera switch GPIO
- RC8_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to control high/low level on PB5 pad
The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200.
Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.
TIPS
- F405-TE has INAV fw preloaded for QC
- set BLHeli32 ESC PWM rate to 48KHz or higher in BLHeliSuite
ArduPilot
- ArduPilot fw, “Internal errors 0x4000 l:213 spi_fail” warining, pls set LOG_BACKEND_TYPE = 1 (File) for SD card logging.
- Download ArduPilot firmware from HERE.
INAV
- With INAV firmware, DSHOT can not work on S3, S5,S7 because of DMA clash, pls use ONESHOT or MULTISHOT and calibrate ESC PWM range.
- Download INAV firmware 4.1.x from our website. INAV5.x or newer directly from INAV configurator
BetaFlight
- If using 5V passive buzzer, CLI “set beeper_frequency = 2500”
- MATEKF405TE_SD target was supported since BF4.4.
- set dshot_bitbang = ON when using X6 and X8 DSHOT,
- You may download BF 4.3 directly from BF configurator, BF 4.2.x from our website (click “Firmwares” button at upper right corner)
- Barometer SPL06-001 is not supported by Betaflight.
