base on BlueNRG-1 SoC from ST. Embedded 2.4GHz transceiver; the EH-ES101module
provides a complete RF solution allowing faster time-to-market with reduced development
costs.
The module offers all Bluetooth® low energy features: radio, stack, profiles and application
space for customer application, so no external control processor is needed. The module also
provides flexible hardware interfaces to connect sensors, simple user interfaces or even
displays directly to the module.

5. Physical Interfaces
5.1. GPIO
14 IOs are provided. Every IO can program for other function.
All theGP IOs are in high impedance under reset. All the IOs are in high impedance
in low power modes (sleep and standby). If pre-programmed as wake up sources,
pins IO9, IO10 and IO11 are in input pull up.
All the GIOs can programed for an interrupt source. Edge detection or level
detection, and falling/rising or both.
GIO0~GIO8 and GIO14 can program input pull down.
GIO9~GIO11 can program input pull up.
GIO12 can only be General Purpose Input pins (not output).

Table 4：Internal Pull for 1.8V
Note: A. GIO7 can work as BOOT pin. when power on, if GIO7 is high level, CPU will jump to bootloader
mode, and this time can update the firmware by UART.
B. GIO9 and DIO10 can work as SWDCLK and SWDIO. If need debug or download also can use Jlink
OB or ST-LINK.
The IOs programmed to be wake up sources need an external drive according to the selected level
sensitivity. If the wake up level is high level, a pull down drive should be used. If the wake up level is low
level, a pull up drive should be used. If no external drive is applied, IO9, IO10 and IO11 are only sensitive
to low level as they have an internal pull up (activated by default). IO12 do not have an internal pull and
therefore require an external drive.
5.2. ADC
2 ADCs are provided.
Main features are: . e pins ADC1 and ADC2.
Internal temperature and battery level conversion.
EH-ES101
Ehong ® Professional Bluetooth Solutions Provider page 8 of 14
5.3. PWM
2 PWMs can be driven by internal PWM module.
5.4. UART
This is a standard UART interface for communicating with other serial devices. The
UART interface provides a simple mechanism for communicating with other serial
devices using the TTL protocol.
When using low-power mode, TXD needs to pull up resistance, and the reference value
is 4.7k.
Main features are:
Programmable baud rate can reach up to 921600bps.
me of 5, 6, 7 or 8 bits of data.
-parity bit generation and detection.
5.5. I2C Master
The module can act as an I2C master when configured by software.
Main features are: e and up to 100 Kb/s in standard mode.
multi-master system with bus arbitration.
5.6. SPI Master
The module can act as an SPI master (mode 0) when configured by software.
Main features are:

Note: A. DC-DC transverter select;
(1) When the DC-DC converter is not used, a 0 - o resistor is welded to the welding plate 1-3,
otherwise it cannot work;
(2) When the dc-dc converter is activated, a 10uH inductance is welded to the welding disc
1-2.This method can reduce peak power consumption, and the peak current can be
reduced by about 45%.
B. Pin23 BOOT pin can’t connect to VCC, or else will always goto boot mode;
C. Pin9 VDD1V2 need connect a test pad.

11. Soldering Recommendations
EH-ES101 is compatible with industrial standard reflow profile for Pb-free solders. The
reflow profile used is dependent on the thermal mass of the entire populated PCB, heat
transfer efficiency of the oven and particular type of solder paste used. Consult the
datasheet of particular solder paste for profile configurations.
SMT stencil making requirements
If Bluetooth module PIN pitch ≥ 0.25mm and other component PIN pitch ≥ 0.25mm,so you
choose SMT stencil thickness 0.15mm.
If Bluetooth module PIN pitch ≥ 0.25mm and other component PIN pitch ≤ 0.25mm,so you
choose SMT Ladder stencil Bluetooth module thickness 0.15mm other component
thickness 0.13mm.
