width=\"869\">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.<br \/>\nIf 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.<\/td>\n<\/tr>\n<tr>\n<td colspan=\"6\"><\/td>\n<\/tr>\n<tr>\n<td rowspan=\"2\">ADC<\/td>\n<td width=\"114\">Vbat sensor<\/td>\n<td width=\"131\">0~30V<\/td>\n<td width=\"190\">1K:20K divider builtin<\/td>\n<td width=\"165\">BATT_VOLT_PIN<br \/>\nBATT_VOLT_MULT<\/td>\n<td width=\"169\">14<br \/>\n21.0<\/td>\n<\/tr>\n<tr>\n<td width=\"114\">Current sensor<\/td>\n<td>0~3.3V<\/td>\n<td width=\"190\">onboard current sense<\/td>\n<td width=\"165\">BATT_CURR_PIN<br \/>\nBATT_AMP_PERVLT<\/td>\n<td width=\"169\">15<br \/>\n40<\/td>\n<\/tr>\n<tr>\n<td colspan=\"6\"><\/td>\n<\/tr>\n<tr>\n<td rowspan=\"3\">I2C<\/td>\n<td rowspan=\"3\">I2C1<\/td>\n<td rowspan=\"3\">5V tolerant I\/O<\/td>\n<td>Compass<\/td>\n<td>COMPASS_AUTODEC<\/td>\n<td>1<\/td>\n<\/tr>\n<tr>\n<td>onboard Baro SPL06-001<\/td>\n<td>Address<\/td>\n<td>0x76<\/td>\n<\/tr>\n<tr>\n<td width=\"190\">Digital Airspeed I2C<br \/>\nMS4525<br \/>\nDLVR-L10D<\/td>\n<td width=\"165\">ARSPD_BUS<br \/>\nARSPD_TYPE<br \/>\nARSPD_TYPE<\/td>\n<td width=\"169\">1<br \/>\n1<br \/>\n9<\/td>\n<\/tr>\n<tr>\n<td colspan=\"6\"><\/td>\n<\/tr>\n<tr>\n<td rowspan=\"10\" width=\"100\">UART<br \/>\n5V tolerant I\/O<\/td>\n<td>USB<\/td>\n<td>USB<\/td>\n<td><\/td>\n<td>console<\/td>\n<td>SERIAL0<\/td>\n<\/tr>\n<tr>\n<td>TX3 RX3<\/td>\n<td>USART3<\/td>\n<td>NO DMA<\/td>\n<td>telem2<\/td>\n<td>SERIAL2<\/td>\n<\/tr>\n<tr>\n<td>TX5 RX5<\/td>\n<td>UART5<\/td>\n<td>NO DMA<\/td>\n<td><strong>GPS1 ***<\/strong><\/td>\n<td>SERIAL3<\/td>\n<\/tr>\n<tr>\n<td>TX4 RX4<\/td>\n<td>UART4<\/td>\n<td>NO DMA<\/td>\n<td><strong>GPS2 ***<\/strong><\/td>\n<td>SERIAL4<\/td>\n<\/tr>\n<tr>\n<td rowspan=\"6\" width=\"114\">TX2 RX2<br \/>\nSBUS<\/td>\n<td>USART2<\/td>\n<td>with DMA<\/td>\n<td>RC input\/Receiver<\/td>\n<td rowspan=\"3\">SERIAL6<\/td>\n<\/tr>\n<tr>\n<td>RX2<\/td>\n<td>IBUS\/DSM\/PPM<\/td>\n<td rowspan=\"2\" width=\"165\">BRD_ALT_CONFIG 0<br \/>\nDefault<\/td>\n<\/tr>\n<tr>\n<td>Sbus pad<\/td>\n<td>SBUS<\/td>\n<\/tr>\n<tr>\n<td>TX2 &amp; RX2<\/td>\n<td>CRSF<\/td>\n<td rowspan=\"3\" width=\"165\">BRD_ALT_CONFIG 1<br \/>\nSERIAL6_PROTOCOL 23<\/td>\n<td width=\"169\">SERIAL6_OPTIONS 0<\/td>\n<\/tr>\n<tr>\n<td>TX2<\/td>\n<td>\u00a0uninverted FPort (hacked)<\/td>\n<td width=\"169\">SERIAL6_OPTIONS 4<\/td>\n<\/tr>\n<tr>\n<td>TX2<\/td>\n<td>SRXL2<\/td>\n<td width=\"169\">SERIAL6_OPTIONS 4<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<ul>\n<li><span style=\"color: #0000ff;\">***\u00a0 If connecting just one GPS to UART4(TX4\/RX4),\u00a0 pls set\u00a0 SERIAL3_PROTOCOL = -1 or non \u201c5\u201d.\u00a0 \u00a0otherwise ArduPilot will stop searching for GPS during bootup if not found on the first port(SERIAL3\/UART5) configured for GPS protocol.\u00a0<\/span><\/li>\n<\/ul>\n<h4>SD card logging<\/h4>\n<ul>\n<li><span style=\"color: #0000ff;\">set LOG_BACKEND_TYPE = 1 (File)<\/span><\/li>\n<\/ul>\n<h4>Frsky Smartport Telemetry<\/h4>\n<ul>\n<li>non-inverted (hacked) S.Port signal<\/li>\n<\/ul>\n<ul>\n<li>any spare Uart_TX<\/li>\n<li>SERIALx_BAUD\u00a0 \u00a057<\/li>\n<li>SERIALx_OPTIONS\u00a0 7<\/li>\n<li>SERIALx_PROTOCOL\u00a0 4\u00a0 or 10(for yaapu)<\/li>\n<\/ul>\n<h4>Relay(PINIO)<\/h4>\n<ul>\n<li>PINIO1,\u00a0 Vbat output ON\/OFF, ON by default<\/li>\n<li>PINIO2,\u00a0 PIO2 pad output Low\/High Level,\u00a0 Low Level by default<\/li>\n<\/ul>\n<p># GPIOs<\/p>\n<ul>\n<li>PA4\u00a0 PINIO1\u00a0 OUTPUT\u00a0 GPIO(81)\u00a0 LOW<\/li>\n<li>PB5\u00a0 PINIO2\u00a0 OUTPUT\u00a0 GPIO(82)\u00a0 LOW<\/li>\n<\/ul>\n<p># RCx_OPTION: RC input option<\/p>\n<ul>\n<li>28\u00a0 \u00a0Relay1 On\/Off<\/li>\n<li>34\u00a0 \u00a0Relay2 On\/Off<\/li>\n<\/ul>\n<p>e.g.<\/p>\n<ul>\n<li>RELAY1_FUNCTION\u00a0 1<\/li>\n<li>RELAY1_PIN\u00a0 \u00a0 \u00a0 \u00a081<\/li>\n<li>RC7_OPTION\u00a0 \u00a028\u00a0 \u00a0 \/\/Use CH7 of Transmitter to control Vbat output ON\/OFF<\/li>\n<li>RELAY2_FUNCTION\u00a0 1<\/li>\n<li>RELAY_PIN2\u00a0 \u00a0 \u00a082\u00a0 \u00a0 \/\/PIO2 pad<\/li>\n<li>RC8_OPTION\u00a0 \u00a034\u00a0 \u00a0 \/\/Use CH8 of Transmitter to control PIO2 Low\/High Level<\/li>\n<\/ul>\n<p>The configured feature will be triggered when the auxiliary switch\u2019s pwm value becomes higher than 1800.
