ATTINY4-TSHR from Microchip Tech, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PB0 | bidirectional | Port B bit 0, a bidirectional I/O pin with selectable internal pull-up and alternate functions PCINT0, TPIDATA, OC0A, ADC0 and AIN0. |
| 2 | GND | power_in | Ground. |
| 3 | PB1 | bidirectional | Port B bit 1, a bidirectional I/O pin with selectable internal pull-up and alternate functions PCINT1, TPICLK, CLKI, ICP0, OC0B, ADC1 and AIN1. |
| 4 | PB2 | bidirectional | Port B bit 2, a bidirectional I/O pin with selectable internal pull-up and alternate functions T0, CLKO, PCINT2, INT0 and ADC2. |
| 5 | VCC | power_in | Digital supply voltage, 1.8 - 5.5V operating range. |
| 6 | PB3 | bidirectional | Port B bit 3 with alternate functions PCINT3 and ADC3. It is also the active-low RESET input, where a low level longer than the minimum pulse length generates a reset, and it can be used as a weak I/O pin. |
