* ADC2 is currently not supported in the micropython firmware 6.1 Remapping Pins The ESP32 features comprehensive pin remapping functionality. This allows peripherals to be mapped onto almost any available GPIO pins. The above table merely shows the default assignments. For example, the default mapping has the SPI and I2C clocks overlapping, meaning both cannot be used simultaneously without remapping one to a different pin. For a detailed guide of what peripheral can be assigned to what pins please read Appendix A ESP32 Pin Lists of the ESP32 datasheet.

Remappable to any GPIO. Note: P1318 can only be mapped to RX since they are input only. TDO = P4, TDI = P9, TCK = P10, TMS = P24 All GPIO except P1318 which are input only 18 Fixed mapping, see Table 1, Only ADC 1 is supported in our micropython firmware. 2 1 Only available on P21 and P22 DAT0 = P8, SCLK = P23, CMD = P4
* Requires an external CAN bus transceiver, we recommend the SN65HVD230 from Texas Instruments. For a more detailed description of the ESP32 peripherals along with peripherals not currently supported by our firmware, please check the ESP32 datasheet. 7.1 RTC Our modules by default all use the internal RC oscillator at 150kHz for the RTC. If you require better accuracy/
stability you can connect a 32.768 kHz crystal (or TCXO) externally on pins P19 and P20 (or P19 for a TXCO) Figure 2 External RTC crystal circuits Version 1.0 08 GPy 8.0 8.1 8.2 9.0 9.1 Programming the device UART By default, the modules run an interactive python REPL on UART0 which is connected to P0 (RX) and P1 (TX) running at 115200 baud. The easiest way to connect to the GPy is via our expansion board, but any USB UART adapter will suffice. Code can be run via this interactive REPL or you can use our PyMakr plugin for Atom or Visual Studio Code to upload code to the board. WiFi By default, the GPy also acts as a WiFi access point. SSID: gpywlanXXXX Password: www.pycom.io Once connected to the GPys WiFi network you can access it in two ways. 8.2.1 8.2.2 Telnet Running on port 23 is a telnet server. This acts in a very similar way to the UART. It presents you with an interactive REPL and can also be used to upload code via PyMakr. FTP The GPy also runs a FTP server that allows you to copy files to and from the device, include an SD card if one is connected. To connect to this FTP server, you need to use plain FTP (unencrypted) with the following credentials User: micro Password: python Boot modes 9.2 Bootloader mode In order to update the firmware of the GPy device, it needs to be placed into bootloader mode. In order to do this, P2 needs to be connected to ground when the device reboots. Once in bootloader mode you can use the Pycom firmware update tool to update to the latest official firmware. If you are developing your own firmware based on our opensource firmware, a flashing script is provided with the source code. Safe boot The micropython firmware features a safe boot feature that skips the boot.py and main.py scripts and goes straight to the REPL. This is useful if the device is programmed with code that causes the device to crash or become inaccessible. To access this mode, you need to connect P12 to 3.3V and reset the device. Upon entering safe boot mode, the onboard LED will begin to blink orange. Depending on the duration the pin is held at 3.3V, a different firmware will be run. Table 3 Boot modes 03 Seconds 36 Seconds Current firmware without running boot.py or main.py Previous firmware if the firmware was uploaded via OTA
(without running boot.py and main.py) Version 1.0 09 GPy 10.0 Power The GPy features an onboard voltage regulator that takes 3.5V 5.5V from the VIN pin and regulates it to 3.3V. It is important to only use the 3.3V as an output and not try to feed 3.3V into this pin as this could damage the regulator. 10.1 Current consumption by power modes/features measured at 3.3V Table 4 Power consumption by feature Mode Idle (no radios) LTE Transmit LTE Attached WiFi AP WiFi client Bluetooth Deep sleep Min Avg. 60 173 74.5 123 134 114 24.0 Max 285 Units mA mA mA mA mA mA A Version 1.0 10 GPy 11.0 Memory Map 11.1 Flash Table 5 Flash memory map Name NVS Description Start address Nonvolatile RAM area.
