# Hisource Hi-K0402WS
-Following is documentation for unmanaged switch marked as `Hi-K0402WS`.
-
-Original software is running UART on 9600 baud rate.
+Following is documentation for unmanaged switch marked as `Hi-K0801WS`.
Using SPI clamp in-board is the only method for initial installation.
-The board has two flash chips `BY25Q16BS` with 16M-bit size. The front switch, switches between the two flash chips.
-These can be programed independently by using said switch - so it is e.g. possible to run the original and new firmware in parallel.

### T2, serial console
-| `J2` pin | Signal |
-| -------- | ----------- |
-| 1 | 3V3 |
-| 2 | RX (Input) |
-| 3 | TX (Output) |
-| 4 | GND |

## Power supply
Input power is delivered via barell plug, `12V 1A` adapter was provided.
-Board has two supply rails. `0.95` and `3.3` volt.
-
-### `0.95` Core Voltage
-
-Voltage is made by a `Techcode TD1720` .
-
-### `3.3` Voltage
-
-Voltage is created by chip marked as `Techcode TD1720`.
-
-**There seems to have been a miscalculation when choosing the inductor and the device is ~25% more efficient with an 5V power supply.**
