How to use
It is very easy just to tie this board to the PC with a USB cable. It is not necessary to
change the setting of the board. The power supply of the module supplies by default
3.3V from 3V3OUT of FT232RQ.

MEMO
1) Current measurment
To measure the current, please cut the shorting 1pin and 2 pin of CN6. And connect an
ampere-meter between the pins of connector CN6 to monitor the current directly.
2) About the power supply of the module
When you use external power supply, please supply power from 9pin and 10pin of CN3.
On this configuration, you cut short circuit 1pin and 2pin of CN5 and should separate
3V3OUT of FT232RQ.
3) USB to serial UART interface
It needs to install driver of FT232RQ to use USB for UART interface.
The drivers are available on FTDI website.

Important notes
The evaluation board included with the Nordic Development Kit uses a 16MHz clock. Therefore the
sample code from Nordic is designed to be used with a 16MHz clock. On the other hand, the
EYSGJN and EYAGJN series module uses a 32MHz system clock, making it incompatible with the
Nordic sample code (i.e. sample code does not configure HFCLK: XTALFREQ register for 32MHz).
To fix this issue, we need to write the value 0xFFFFFF00 to the UICR (User Information
Configuration Register) at address 0x10001008. Please note that the UICR is erased whenever you
download a SoftDevice.
The UICR can be written by using the debug tools:
nrfjprog.exe --snr <your_jlink_debugger_serial_number> --memwr 0x10001008 --val 0xFFFFFF00
Or the following code can be added to the SystemInit function in the system_nRF51.c file, right
before launching the TASK_HFCLKSTART task:
if (*(uint32_t *)0x10001008 == 0xFFFFFFFF)
{
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Wen << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
*(uint32_t *)0x10001008 = 0xFFFFFF00;
NRF_NVMC->CONFIG = NVMC_CONFIG_WEN_Ren << NVMC_CONFIG_WEN_Pos;
while (NRF_NVMC->READY == NVMC_READY_READY_Busy){}
NVIC_SystemReset();
while (true){}
}
32kHz Clock
This module does not installed 32.768kHz crystal. In case of operating without external crystal,
please use following example code in order to enable internal 32.768kHz RC oscillator (32k
RCOSC).
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, false);
Note that when you choose to use the RC oscillator, it will add around 10uA average current
consumption compared to a 20ppm external crystal.
