-### ESP32 DRAM Configuration
54
-
55
-ESP32 has **520 KB SRAM** split into multiple regions:
56
-
57
-- **DRAM0**: 192 KB - Main data RAM for variables and heap
58
-- **DRAM1**: 128 KB - Instruction RAM cache (can be used as data RAM)
59
-- **DRAM2**: 200 KB - Used by WiFi/Bluetooth stack and DMA buffers
60
-
61
-**Key Points:**
62
-- **Internal DRAM**: Fast access, used for critical data and stack
63
-- **External PSRAM**: Optional 4-8MB external RAM (via SPI)
64
-- **DMA Capable**: Some regions support DMA operations
65
-- **Shared Memory**: WiFi/BT libraries consume significant DRAM
66
-
67
-**Memory Management:**
68
-- Heap allocation uses internal DRAM first
69
-- Large buffers should use PSRAM when available
70
-- Use `esp_get_free_heap_size()` to monitor usage

-The PCF8591 is a single-chip, single-supply low-power 8-bit CMOS data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware. Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus.

+The `RP2354` is a secure, high-performance microcontroller from Raspberry Pi that is identical to the RP2350 but features an additional 2MB of QSPI NOR flash memory stacked directly inside the package. It is available in two pin-compatible package variants: the 30-pin RP2354A and the 48-pin RP2354B.

7
+The ENS160 is a digital multi-gas sensor solution, based on metal oxide (MOX) technology
8
+with four sensor elements.
9
+
10
+The independent hotplate control allows the detection of a wide range of volatile organic
11
+compounds (VOCs) including ethanol, toluene, hydrogen and oxidizing gases with superior
12
+sensitivity. The ENS160 supports intelligent algorithms to process raw sensor measurements
13
+on-chip. These algorithms calculate CO2-equivalents, TVOC, air quality indices (AQIs) and
14
+perform humidity and temperature compensation, as well as baseline management, all on
15
+chip.
16
+
17
+Raw sensor measurements can be read for further customization. The LGA-packaged device
18
+includes SPI and I²C slave interfaces to communicate with a main host processor.
19
+The ENS160 is a proven and maintenance-free technology, designed for high volume and
20
+reliability.

-1. **ADC Ctrl LOW (0V):**
61
- - Q8 is **OFF** (no base current).
62
- - The gate of Q7 is pulled up to VBAT via R30.
63
- - Q7 (P-MOSFET) is **OFF** (Vgs ≈ 0V).
64
- - No voltage is present at BAT_ADC; the voltage divider is disconnected from VBAT.
65
- - **ADC input is isolated** (saves power, prevents leakage).
66
-
67
-2. **ADC Ctrl HIGH (e.g., 3.3V or 5V):**
68
- - Q8 is **ON** (base current flows via R9/R25).
69
- - Q8 pulls the gate of Q7 **towards GND** through R31.
70
- - Vgs of Q7 becomes negative (gate lower than source), **turning Q7 ON**.
71
- - VBAT is now connected to the voltage divider (R32/R33).
72
- - The divided voltage appears at **BAT_ADC** for ADC measurement.
73
-
74
-### Purpose
75
-
76
-- **Power Saving:** Only connects the voltage divider to the battery when ADC measurement is needed, reducing continuous current drain.
77
-- **Control:** Allows the microcontroller to enable/disable battery voltage sensing.

+1. **ADC Ctrl LOW (0V):**
61
+ - Q8 is **OFF** (no base current).
62
+ - The gate of Q7 is pulled up to VBAT via R30.
63
+ - Q7 (P-MOSFET) is **OFF** (Vgs ≈ 0V).
64
+ - No voltage is present at BAT_ADC; the voltage divider is disconnected from VBAT.
65
+ - **ADC input is isolated** (saves power, prevents leakage).
66
+
67
+2. **ADC Ctrl HIGH (e.g., 3.3V or 5V):**
68
+ - Q8 is **ON** (base current flows via R9/R25).
69
+ - Q8 pulls the gate of Q7 **towards GND** through R31.
70
+ - Vgs of Q7 becomes negative (gate lower than source), **turning Q7 ON**.
71
+ - VBAT is now connected to the voltage divider (R32/R33).
72
+ - The divided voltage appears at **BAT_ADC** for ADC measurement.
73
+
74
+### Purpose
75
+
76
+- **Power Saving:** Only connects the voltage divider to the battery when ADC measurement is needed, reducing continuous current drain.
77
+- **Control:** Allows the microcontroller to enable/disable battery voltage sensing.

+### Summary Table

+
81
+| ADC Ctrl | Q8 (NPN) | Q7 (P-MOSFET) | BAT_ADC Output |
82
+|----------|----------|---------------|---------------------|
83
+| LOW | OFF | OFF | Disconnected (0V) |
84
+| HIGH | ON | ON | Battery voltage via divider |
85
+
86
+---
87
+**In summary:**
88
+`ADC Ctrl` enables or disables the battery voltage divider connection to the ADC
