First Impressions
Seems pretty easy to open up. One philips screw from the front. (Needs a skinny screwdriver tho...)
First thing you see is the important part (From a hacking viewpoint).
There're actually 2 boards with a 4x2 interconnect.
All the power stuff is on the one on the right.
The one on the left is the WiFi & RF board.
Notes
There are 4 chips on the WiFi & RF board:
| Label | Part | Notes |
|---|---|---|
| U1 | Eastsoft ES7P001FGSA GS34BFN404 | 8-bit MCU? |
| U2 | 590R 1933 | Probably the RF chip |
| U3 | BB10 F8G A01J1J 1939 A | 8-bit MCU |
| U5 | ESP8285 |
There are 7 test points immediately accessible on the board:
| Label | Signal | ESP
Pin |
Notes |
|---|---|---|---|
| TP3 | EXT_RSTB | 32 | Possibly useful for reset when flashing? |
| 5 | GPIO5 | 24 | |
| 4 | GPIO4 | 16 | |
| 0 | GPIO0 | 16 | |
| 6 | GPIO2 | 14 | |
| RX | UORXD | 25 | Also connected to U3 pin 17 via 0Ω resistor R16 |
| TX | UORXD | 26 | Also connected to U3 pin 18 via 0Ω resistor R15 |
This board has 2 4-pin header locations.
J1 seems to connect to U3.
| Pin | Label | |||
|---|---|---|---|---|
| 1 | 3v3 | toward edge | ||
| 2 | C2CK | U3 | 5 | |
| 3 | C2D | U3 | 6 | |
| 4 | GND | toward centre |
J4 connexts to RX & TX on the ESP chip.
| Pin | Label | |||
|---|---|---|---|---|
| 1 | 3v3 | toward edge | ||
| 2 | E-RX | U5 | 25 | |
| 3 | E-TX | U5 | 26 | |
| 4 | GND | toward centre |
The interconnect to the power board:
| Label | Pin # | Label | Connects to | ||
|---|---|---|---|---|---|
| GND | 1 | BUZZER | U3 pin 1 | toward centre | |
| GND | ZERO_CROSS | U3 pin 20 | |||
| GND | CONTROL | U3 pin 13 | |||
| 3v3 | 3v3 | toward edge | |||
There are 2 switch locations on the board.
S1 is un-populated but seems to be for a push-button on the ESP chips GPIO0 pin.
S2 is a slide switch labelled "OTA" (Not the default position...). This switch appears to be accessible through a small slot in the front cover of the unit.
