111		-The board has 9 distribution circuits, one for each fused output group. All 9 circuits use the same design, and the component reference designators follow the circuit number (circuit 1 uses R101–R104, C101, D101 and F101, circuit 2 uses R201–R204, and so on). Each circuit consists of:
112		-
113		-* A fuse in a Littelfuse nano fuse holder, so the fuse can be replaced without soldering
114		-* A 2 mΩ shunt resistor for current measurement
115		-* A current sense amplifier channel and a low-pass filter to the microcontroller ADC
116		-* An RGB LED, where the green channel shows that the fuse is intact and the red channel is controlled by the microcontroller

129	129	=== Green LED ===
130	130
131		-The green LED indicates whether the fuse is intact. It is connected from the output side of the fuse to ground through a 4.7 kΩ resistor. When the fuse is intact, the LED lights up. If the fuse blows, the LED loses its supply and turns off. This makes it easy to find a blown fuse by looking at the board.
	122	+The green LED is used to see if the fuse is ok
132	132
133		-The LED is powered directly from the output voltage, so the current depends on the supply. At 24 V the current is roughly 4–5 mA, and at 12 V it is about 2 mA. This turned out to be brighter than necessary.

138	138
139		-The current in each circuit is measured by passing it through a shunt resistor with a very low resistance and measuring the voltage drop across it. This small voltage is amplified, filtered and read by the microcontroller's ADC.

142	142
143		-A 2 mΩ shunt resistor is placed in series with the load. The voltage drop across it is 2 mV per ampere of current (0.002 V/A).
	132	+A resistor with 2mOhm is in series to measure the voltage drop over the resistance that gives a voltage of 0.002 ever Amp of current
144	144
145		-The shunt is a Vishay WSLF2512 metal strip resistor with 1 % tolerance and a 5 W rating. The low resistance keeps the losses small: at 8 A the voltage drop is only 16 mV and the power loss is about 0.13 W.

151		-The amplifier is a quad-channel current sense amplifier with a gain of 200 V/V. When the measured voltage drop passes through the amplifier, the output is therefore 0.4 V per ampere.
	138	+the amplifier is a quad chanel amplifier with a gain of 200V/V. So when the measured voltage drop is passed trough the amplifier it will give 0.4V per 1A.
152	152
153		-The board uses three INA4180A4 amplifiers (U3, U4, U5) from Texas Instruments. This gives 12 channels, of which 9 are used. The INA4180 measures on the high side and accepts a common-mode voltage of up to 26 V, so it can measure directly on the 24 V outputs.
154		-
155		-With the 3.3 V ADC on the microcontroller, the maximum measurable current is about 8 A (3.3 V / 0.4 V/A ≈ 8.25 A). Above this, the amplifier output saturates.

167		-It is an RC filter made of a 10 kΩ resistor and a 10 nF capacitor between the amplifier output and the ADC pin: f,,c,, = 1 / (2π × 10 kΩ × 10 nF) ≈ 1.6 kHz. The filter removes high-frequency noise, for example from PWM-controlled fans and switching loads, before the signal is sampled. The capacitor also acts as a charge reservoir for the ADC's sampling capacitor.

178		-
179		-The input voltage is calculated in firmware as V,,in,, = V,,pin,, × 11. With a 3.3 V ADC, the highest voltage that can be measured is about 36 V, which gives good margin above the 24 V supply.

211		-* **3.3 V:** An AP2112K-3.3 LDO regulator (U7) generates 3.3 V for the microcontroller and the current sense amplifiers.
212		-* **CAN bus:** An NCV7344 CAN FD transceiver (U2) connects the microcontroller to the CAN bus. The transceiver supports up to 5 Mbps, and the bus runs at 1 Mbps. A common-mode choke (L1) reduces noise on the bus lines, and a TVS diode (D1) protects them against ESD and voltage spikes.

214		-The whole board is protected by a 400 W power TVS diode (D2) on the input, which clamps voltage spikes on the supply.

	172	+The programable red light is in the same RGB LED Diode
221	221
222		-Current is sourced directly from the microcontroller through a 350 Ω series resistor. When the pin is driven high (3.3 V), current flows through the resistor and the red LED to ground. The STM32 pins can supply up to about 20 mA each, so no transistor is needed. This gives an LED current of roughly 3–4 mA, which made the LEDs too bright. The resistor value should be increased on the next version.

228		-The buzzer, brake light and pumps are switched on the high side. The load's negative side is permanently connected to ground, and the controller switches the positive supply. This means a short from the output wire to chassis cannot turn the load on, and the load is completely unpowered when it is off.

230		-Each output uses a P-channel MOSFET as the main switch between the supply and the load. A P-channel MOSFET is used because it can switch the high side without a charge pump or gate driver. It turns on when its gate is pulled below its source (the supply voltage).

231	231
232		-The microcontroller runs on 3.3 V and cannot pull the gate of the P-channel MOSFET far enough on its own. A small N-channel MOSFET is therefore used as a level shifter:

233	233
234		-* **Output off:** The microcontroller pin is low, so the N-channel MOSFET is off. A pull-up resistor holds the P-channel gate at the supply voltage, so V,,GS,, = 0 V and the P-channel MOSFET is off.
235		-* **Output on:** The microcontroller pin goes high (3.3 V) and turns on the N-channel MOSFET. This pulls the P-channel gate towards ground, V,,GS,, becomes negative and the P-channel MOSFET turns on.
	186	+The nchannel mosfet(BSS123NH6327XTSA1) is th same as the buzzer/brake light but the pchannle mosfet(BSS123NH6327XTSA1) is a pchannel mosfet with a higher rated current the

242	242
243		-These outputs run on 24 V. The BSS83P is rated for -60 V and -0.33 A, which limits each output to 330 mA. This is enough for the buzzer and an LED brake light. The maximum gate-source voltage of the BSS83P is ±20 V, so the gate must not be pulled all the way to ground from 24 V. The two 10 kΩ resistors on the P-channel gate form a voltage divider that limits V,,GS,, to about half the supply (≈ -12 V).

259		-The pumps run on 12 V and draw considerably more current. The BSC084P03 is a power MOSFET rated for -30 V and -78.6 A, with an on-resistance of about 8.4 mΩ. At 5 A this gives a loss of only about 0.2 W, so no heatsink is needed. Since the supply is 12 V, the gate can be pulled fully to ground without exceeding the ±20 V gate-source rating.
